1904165 - slow startup on first open Firefox ESR 115.12

Status: NEW

(WebExtensions :: Untriaged, defect, P3)

Description

[alannsandiego]

User Agent: Mozilla/5.0 (Windows NT 6.1; Win64; x64; rv:109.0) Gecko/20100101 Firefox/115.0

Steps to reproduce:

Since Firefox ESR 115.12 updated Firefox with extensions takes 12 seconds to start the first time, new tabs or windows not a problem. However since Firefox is the default browser and not running until started, start time is a problem, cannot type text until 12 seconds. https://snipboard.io/QF0ERT.jpg
In troubleshooting mode without extension it does start faster but the extension was not a problem before your update.

Actual results:

First startup of Firefox ESR 115.12 always 12 second about every time.
I tried to test the startup speed but was unable to, say cannot find profile for this tab. https://firefox-source-docs.mozilla.org/performance/reporting_a_performance_problem.html
https://profiler.firefox.com/docs/#/./guide-getting-started
https://profiler.firefox.com/
I found a test but I could not get it to work, it say cannot find profile, and cannot load profile in 30 seconds etc.

Expected results:

First startup of Firefox ESR 115.12 should take no more than 2 seconds at the most.

[BugBot [:suhaib / :marco/ :calixte]]

The Bugbug bot thinks this bug should belong to the 'WebExtensions::Untriaged' component, and is moving the bug to that component. Please correct in case you think the bot is wrong.

Since this seems to be a startup performance issue, you should set the MOZ_PROFILER_STARTUP=1 environment variable before starting Firefox, as mentioned at https://profiler.firefox.com/docs/#/./guide-startup-shutdown

Have you tried this in order to capture a performance profile?

I do not know how to set environment variables and this tool did not work at all I got these several errors.

I have many extensions but I have not changed them in years, what changed due to the Firefox updates,
is the startup time from 1 second to 12 seconds; I do not really know how to tell objectively what to fix.
Disabling two ad-blockers reduces the startup time for 12 seconds to 6 second, but before the updates,
Firefox did in fact startup in 1 second with all the extensions in place.

Please attach the output of about:support too.

To set an environment variable for a specific Firefox instance:

1. Open a text editor such as Notepad.
2. Copy paste the following content (assuming a default Firefox installation; change if needed)

SET MOZ_PROFILER_STARTUP=1
"C:\Program Files\Mozilla Firefox\firefox.exe"

3. Save the above as debug_firefox_startup.bat (make sure that the file extension is .bat and not a .txt file!)
4. Quit all existing Firefox programs.
5. Double-click on the bat file to launch Firefox.

Also, can you please let me know what extensions are installed on your profile when FF is started?

Thanks,

Please attach the output of about:support too.

To set an environment variable for a specific Firefox instance:

1. Open a text editor such as Notepad.
2. Copy paste the following content (assuming a default Firefox installation; change if needed)

SET MOZ_PROFILER_STARTUP=1
"C:\Program Files\Mozilla Firefox\firefox.exe"

3. Save the above as debug_firefox_startup.bat (make sure that the file extension is .bat and not a .txt file!)
4. Quit all existing Firefox programs.
5. Double-click on the bat file to launch Firefox.

---

SET MOZ_PROFILER_STARTUP=1

"C:\Program Files\Mozilla Firefox\firefox.exe"

3. Save the above as `debug_firefox_startup.bat` (make sure that the file extension is .bat and not a .txt file!)
4. Quit all existing Firefox programs.
5. Double-click on the bat file to launch Firefox

I was unable to get your script to run by double clicking it.
I was able to get your script to run by starting in a powershell window but does not even start Firefox
even though the path is correct and does run the script as the output.txt file get created.

PS C:\Users\SystemAdmin2\Desktop> .\debug_firefox_startup.bat >output.txt
PS C:\Users\SystemAdmin2\Desktop> .\debug_firefox_startup.bat >output.txt
PS C:\Users\SystemAdmin2\Desktop>

this make the output.txt file and does not start Firefox.

I do not know how to set environment variables and this tool did not work at all I got these several errors.
https://snipboard.io/XiOa0p.jpg
https://snipboard.io/TUfuvw.jpg
https://snipboard.io/MTXoa0.jpg
I have many extensions but I have not changed them in years, what changed due to the Firefox updates,
is the startup time from 1 second to 12 seconds; I do not really know how to tell objectively what to fix.
Disabling two ad-blockers reduces the startup time for 12 seconds to 6 second, but before the updates,
Firefox did in fact startup in 1 second with all the extensions in place.

I was able to start the performance tool and got these error above by installing he button describe here:

I happy yours works but mine is still broken. If yours work and mine does not does that imply that the updated corrupted Firefox?
So How do I determine what the problem is? Would it not take days to reinstall Firefox to each six account and reinstall bookmarks and extensions?

12 second to startup is far to long. How do I determine what the problem is? Clearly there is problems with the profile. How do I fix my install of Firefox ESR 115.12, in a reasonable amount of time; so it starts up fast like it is suppose too?

Comment 14

[alannsandiego]

the profiler works with the extension disabled: https://share.firefox.dev/3VLLde6
does that not mean the extension are causing the problem?

Comment 15

[Rob Wu [:robwu]]

Your profile does not include the startup. If the profiler works with extensions disabled, perhaps one of your extensions is responsible for breaking the profiler.

There is another documented profiler option to save the profile on shutdown, could you try to start your Firefox with the following environment variables:

SET MOZ_PROFILER_STARTUP=1
SET MOZ_PROFILER_SHUTDOWN=%TMP%\profilerData.json

If you start Firefox with these and then quit it, there should be a file in %TMP% called profilerData.json (feel free you use any other file location or name, but if you do use another file path that contains special characters such as spaces, quote it).

After getting this profile, you can start a new Firefox instance without extensions, visit profiler.firefox.com and upload your profile.

The Firefox update to 115.12 ESR broke Firefox or the extensions which are part of Firefox
and that is the reason for the bug report; Firefox was working before the update and
now it starts in 12 seconds; the extension have not changed in years, so the extension did not break Firefox.

I have not gotten any scripts to open Firefox and I cannot do anything with a .json file

How to I determine what to fix? to get Firefox working in 1 second again?

In comment 7 you described that you knew how to create a bat file.

In fact you showed that you knew how to open the shell (assuming that PS = Powershell). You don't need a .bat file if you run these commands from the shell (NOTE: quit all existing instances of Firefox before running this)

SET MOZ_PROFILER_STARTUP=1
SET MOZ_PROFILER_SHUTDOWN=%TMP%\profilerData.json
"C:\Program Files\Mozilla Firefox\firefox.exe"

After running Firefox in this way, quit Firefox and then start it again in the normal way. You should be able to find a new file at "%TMP%\profilerData.json`

I got the profiler started working by turning off "new tab" and "no tab"

It appears that the shell script you wrote that the profiler is still not starting when Firefox starts,
I started it manually as soon as it was available. The time start a "1" but profiler not starting when Firefox starts.

If I copy this code into the Powershell Firefox gets opened by the code above
and I click on "record a performance profile" button as quickly as I can to start recording,
as the recording is not starting when Firefox does, it starts with record button,
The time may start at "1" but recording not start until I click record,
but the file profilerData.json does not get created.

It would seem simpler to
Start-Process -FilePath "C:\Program Files\Mozilla Firefox\firefox.exe" -profiler_startup=1
and Firefox should startup with recording on and one only needs to stop to get the profiler link?

I will be very interest to see what you think of the profiler data as I record 6 seconds of the 12 seconds to startup
and at least 3 or 4 second of the problem-ed startup time; you should be able to see what the problem is?
looks like waiting on the network to me; or waiting for a network socket? Firefox crashed on 6/11/2024 the update day.

Comment 23

[Rob Wu [:robwu]]

The most important part of the profile (the early startup) is missing. But your profiles do already highlight one issue that may be a partial contributor to the perceived slowness.

All your profiles consistently show busy activity in the WebExtensions process, notably in Adblock Plus and Adblock Ultimate. In order to block ads, these extensions pause all network requests until they have been initialized, and a slow initialization can result in a perceived slow Firefox startup.
In the about:support data you shared, I see that you have three ad blockers: Adblock Plus, Adblock Ultimate and uBlock Origin. I recommend using only one adblocker at a time, and disabling the others. For example, keep uBlock Origin and disable Adblock Plus and Adblock Ultimate.

You can see the impact of the performance in the profiler by entering "adblock" in the "Filter stacks" input field in the middle (which matches "adblock plus" and "adblockultimate"). That highlights almost half of the stacks in the graph in the WebExtensions row, which means that these extensions alone are doing busy work. The long chunks of red lines above these stacks also show that the slowdown is significant.

Correction; this would be the Powershell syntax to record the profile (since you are now able to export the profile directly, I only kept MOZ_PROFILER_STARTUP=1)

$env:MOZ_PROFILER_STARTUP="1"
Start-Process -FilePath "C:\Program Files\Mozilla Firefox\firefox.exe"

You have proof that with the profiler data that Firefox ESR 115.12 starts in 9 seconds not the 1 second before the update with the same extensions.

https://share.firefox.dev/3zhNkif

Load 4: http://detectportal.firefox.com/canonical.html on the network take 5 seconds to load this is a WiFi check for login

Load 59: https://publicsuffix.org/list/public_suffix_list.dat on the network take 4.6 seconds to load

Load 60: https://cococut.net/pub/config/config.json?v=1719789870702 take 4.5 second to load

Firefox is suppose to start in 1 second not 9 seconds even with the ad-blockers
With the profiler data now? can you see why it is so slow?

https://share.firefox.dev/3zhNkif

Both profiles confirm what I wrote before - network requests at startup are being suspended because of your ad blockers. Three ad blockers at the same time are a certain factor in the poor experience, and will not make you more protected, since these usually block ads based on similar filters. Based on the profile, I recommend disabling AdBlock Ultimate and Adblock Plus; uBlock Origin appears to have the lowest startup overhead. If you do this, I expect your situation to improve; if the issues continue please share another performance profile.

From the profile, about 3 seconds of slowness may potentially be attributed to Firefox. I'm especially suspicious of the slowness of handling the storage.local.get call, but it is not as excessive as bug 1899015.

Here is a breakdown of these profiles, focused on the three ad blockers that block resolution of network requests, and one observation that blocks the main thread of the extension process:

• 1 second in - first network request is requested. Extension startup is requested.
• 2 seconds in, AdBlock Plus starts, AdBlock Ultimate and uBlock Origin start loading (among others)
• 2.332 seconds in, storage.local.get API is called by Adblock Plus, which takes 3.268s to resolve (!!!) in https://share.firefox.dev/3zhNkif (in the other profile it takes 2.794 seconds)
  • this can be seen in the Marker Table of the WebExtension process, filter on d10d0bf8-f5b5-c8b4-a8b2-2b9879e08c5d
  • Interestingly, 2.997 seconds in, storage.local.get API is called by Adblock Ultimate, which interestingly takes "only" 0.739 seconds to resolve.
  • This slowdown reminds me of bug 1899015 (analysis at https://bugzilla.mozilla.org/show_bug.cgi?id=1899015#c1).
• 2.5 seconds in, the main thread of the WebExtensions process seems to be blocked for about half a second, waiting on ModuleGenerator::finishOutstandingTask (previous link goes to m-c, since the profile is captured on ESR115 this link is more accurate). The specific file is 499.background-redux.js (622kb) in the Lastpass Password manager add-on (version 4.127.0.1, xpi link) (this add-on itself is almost 120 MB...).
• 3 seconds in, Adblock Ultimate starts.
• 3.807 seconds in, uBlock Origin calls storage.local.get which takes 1.673 seconds to resolve.
• 4 seconds in, AdBlock Ultimate initializes its own ad blocking engine, which takes 1.3 seconds, and then releases the request at 5.5 seconds.
• 5.8 seconds in, uBlock Origin releases the network request. Unlike the other two adblockers, the main thread is barely blocked.
• Almost 6 seconds in, AdBlock Plus receives the data, takes about 600ms to initialize and finally releases the network request.

Comment 29

[Rob Wu [:robwu]]

Jan, my analysis of the profile attributes 3 seconds of startup slowdown to slow IndexedDB. Does the profile show anything that stands out to you? Would this be addressed by bug 1671932? Do you have any recommended actions for users to avoid the slowdown?

Comment 30

[Rob Wu [:robwu]]

Ryan, the profile above (comment 28) shows that the main thread of the WebExtensions process is blocked for about a half second in ModuleGenerator::finishOutstandingTask, waiting on a condition variable associated with code compilation. The relevant code is 622kb and contains "use asm"; (see comment 28 for details).

Blocking the main thread for so long seems excessive. Is this intended behavior? Is there room for optimization?

Here are the specific parts of two distinct startup profiles that show this impact:

• https://profiler.firefox.com/public/ca563x5rzc76hcef4mhqw5hhn6ebz1zyyj4xdw0/calltree/?globalTrackOrder=90w8&hiddenGlobalTracks=1w7&hiddenLocalTracksByPid=7896-0w24w6~10752-0~14488-0~10188-0~7796-0~13044-023~12832-0~1808-013w6~12712-23&range=2112m670&search=finishOutstandingTask&thread=g&v=10

Comment 31

[Jan Varga [:janv]]

I don't see QM I/O thread in the profile, so I can't tell for sure, but yes, if this slowdown is caused by storage initialization, then issues like that will be solved by bug 1671932. However, a big slowdown should be observed only after updating the app (when build id changes).
One solution would be reducing the number of origin directories in <profile>/storage/default or just refreshing the profile entirely.

I understood that part. What I don't know off the top of my head is the set of environment variables that the user need to specify in order to capture the profile you are looking for. After digging through the source code, I think that QuotaManager IO is the thread of interest, and that the reporter has to start Firefox like this:

$env:MOZ_PROFILER_STARTUP_FILTERS="GeckoMain,Compositor,Renderer,DOM Worker,QuotaManager IO"
$env:MOZ_PROFILER_STARTUP="1"
Start-Process -FilePath "C:\Program Files\Mozilla Firefox\firefox.exe"

Comment 35

[alannsandiego]

https://share.firefox.dev/4br98Wi Here is the profiler with QM I/O thread

Yes of course if I reduce the number of ad-blockers Firefox will load faster by 1/2 maybe 4 seconds
but I have never seen Firefox load longer than 1 second until update to ESR115.12

Comment 36

[Rob Wu [:robwu]]

Thanks for the profile. The QuotaManager IO thread doesn't look too busy.

Upon taking another look, I think that the 3 seconds slowdown is not caused by Firefox, but by your add-ons. I zoomed in on the 4 second range 2 seconds after startup, where the graph contains many red bars (=main thread busy): https://profiler.firefox.com/public/w9nz3f6jhh7h731tepg3rzwpb8b578ca7d7wkk0/calltree/?globalTrackOrder=90w8&hiddenGlobalTracks=1w7&hiddenLocalTracksByPid=7056-0235w7~12924-0~3688-0~10212-0~10080-0~10352-023~8388-013w6~5340-0~10976-23&range=1847m4138~2219m3766&thread=h&v=10

• 2.3 seconds in, 526ms jank, flame graph shows that most time spent in ModuleGenerator::finishOutstandingTask (which I called out before in comment 30 & comment 28)
• 2.8 seconds in, 86ms jank, from executing AdBlock Plus. 66ms of that is from a call to OffscreenCanvas.getContext, part of AdBlock Plus's checkWebGlSupport function.
• 3.0 seconds in, 500ms jank, from executing LastPass code.
• 3.6 seconds in, 146ms jank, from executing Norton Password manager code.
• 3.9 seconds in, 100ms jank, 25ms to receive the result from IndexedDB, 65ms to structurally clone again into the sandbox of the Adblock Ultimate extension. This must be a big chunk of data, likely the filter list data.
• 4.0 seconds in, 52ms jank + non jank, total of about 100ms of receiving and processing IndexedDB data, the result of storage.local.get
• 4.1 seconds in, 174ms spent on garbage collection (non-blocking).
• 4.3 seconds in, 1.4 seconds (!!!) spent on adblock ultimate.
• 5.7 seconds in, end of jank from adblock ultimate.
• 5.9 seconds in, 544ms jank, from Adblock Plus initializing itself from its own filter lists.
• 6.5 seconds in, end of jank from Adblock Plus.
• 6.8 seconds in, 1.3 seconds (!!!) spent on garbage collection (non-blocking).

I could analyze more, but from this analysis, it is clear that the time spent on executing extension code adds up. And that the WebExtension process's main thread is so busy that the result from IndexedDB (for storage.local.get) could not be processed for a "long" time because the main thread was simply too busy with other stuff.

Again, this profile strongly suggest that Adblock Ultimate and Adblock Plus are doing a lot of work (and also LastPass), which directly contribute to your perceived slow startup. It is possible that the ESR 115.12 update had nothing to do with the issue, and that it just coincided with the issue you're experiencing from these extensions.

Since this profile (and the previous ones) clearly point to Adblock Plus and Adblock Ultimate as a direct cause of the performance issue, can you try disabling them and then record a new profile? You have uBlock Origin already, which already provides the functionality that these others serve.

Comment 37

[alannsandiego]

To simplify that Adblock Plus and Adblock Ultimate are not the problem I disabled them
and here are the results:
https://share.firefox.dev/3W38sBM
With the two adblockers remove takes 6 seconds to load instead of 1 second at the most, why?
Load 55: https://publicsuffix.org/list/public_suffix_list.dat still taking 2.6 seconds to load why?
Load 56: https://cococut.net/pub/config/config.json?v=1719882301142 2.3 second to load? why?
Load 4: http://detectportal.firefox.com/canonical.html is on the second 500ms Jank This is a WIFI error and I have Wire Cat 8.
there are 5 Janks in the first 1.1 seconds why?
between 2 sec and 3.1 seconds still 500ms Janks and total of 4, why?
https://www.mozilla.org/en-US/security/advisories/mfsa2024-19/
https://www.mozilla.org/en-US/security/advisories/mfsa2024-26/
Do you ever expect Firefox to startup longer than 1 second? because I have never seen that.
Hopefully easier to see why with the Adblockers disabled, they are not the real problem.
I can do a restore of my computer to 6/10/2024 to show that this slowness is new?

Comment 38

[alannsandiego]

Your profiler tool is impressive even if I cannot see all the details, could it be a network problem?
Load 4: http://detectportal.firefox.com/canonical.html is on the second 500ms Jank This is a WIFI error and I have Wire Cat 8.
starts at .75 second and goes to 2.2 seconds; then follow by Load 56: https://cococut.net/pub/config/config.json?v=1719882301142 2.3 second to load? why? that is 5 second also all the missing time?
also
Load 6: https://aimcmp.com/ waiting for socket thread 3.9 second that is basically all the missing time? if loaded right away 2 seconds.

It seem absurd to me that your browser would take 6 seconds to load a webpage.
Firefox loads in 2 second but even that is to long, should be 1/2 second.
what is Firefox doing this first .75 second?
what is firefox doing at 1.2 seconds to 1.6 second jank 604 ms it seems to be doing nothing; should be able to get all that time back how?
and 3.0 to 3.5 doing nothing again. Load 3: http://detectportal.firefox.com/canonical.html time here is (very short); so this is a bug on the older machine with no WiFi? as has both wired and WiFi both looks like 3 networks on newer machine

It is not physical disk i/o or cpu or ram is 32GB on new machine. This should be an interesting comparison, the newer machine Main19 is very high end machine and Main19 is not at fault your browser not loading in 2 seconds. almost the same add-ons on purpose and adblock plus and ultimate both turned off.

With the profiler working so well I would think you and your friends would see why Firefox not starting up in < 2 second and not 6 seconds?

Users think that a browser that more than 3 seconds generously or (1) second actually to open is not useful or practical. Not all the extension have to load on the First startup, before a webpage loads, maybe that would help? Maybe you can load some extension after the first webpage loads? I have not changed the extensions in years and yet Firefox after updates is 9 times slower than it was only 3 months ago; from 1 second to 9 seconds; the Firefox updates damaged Firefox; and that is just not useful any more. This slow startup is a bug no matter the cause; that is why I filed this bug report so you can fix it. If extensions have to be reloaded after Firefox updated you should have a process for that.
Chrome was installed at the same time with the same extensions the same number of ad-blockers and it has not slowed down, why? Why Firefox? It does not matter if Firefox or extensions in the end it is all Firefox without extension it is not useful. If you need to reset Firefox, before resetting make a list of extension, export extensions list; to reinstall and then reinstall Firefox the same way with the same extension to ALL the user accounts at once; right now it take to much time to reinstall Firefox to fix it; you should fix this.

$env:MOZ_PROFILER_STARTUP_FILTERS="GeckoMain,Compositor,Renderer,DOM Worker,QuotaManager IO"
$env:MOZ_PROFILER_STARTUP="1"
Start-Process -FilePath "C:\Program Files\Mozilla Firefox\firefox.exe"

Your profiler tool successfully showed that after the Firefox update ESR 115.12 Firefox started-up in 9 second, instead of the normal
less than 1 second; Firefox was working before your update and was not slow; so Firefox is the problem, it was not slow before your update
either the most recent 12 or 10 I do not know which one but one cannot miss the Browser starting up in 10 second instead of 1 second.

So I started this bug to find out how to fix Firefox will all the extension that were working before and so it will start normally in less than 1 second?
now that Firefox is damaged by the push out updates. How exactly do I Fix Firefox? Yes I have a lot of extensions, but it was working before, now what?

I think the problem is with the last two updates to Firefox since Firefox was working before then,
the the problems with your browser could be determined by someone that understands the last two updates
and the profiler results; but I do not understand the details enough to really even guess more than that.
None the less I need Firefox my default browser working?

It's hard to tell what's going on with asm.js compile blocking for .5sec because the interesting work (compilation) is happening on background threads. I think enabling 'TaskController' threads will show that. However, it seems very plausible that compiling about a megabyte of asm.js could could take .5 seconds to be compiled on multiple background threads.

We could maybe try to rework how JS script parsing works so that we don't block on asm.js compilation completing before returning a stencil, but that would be a large project and we're not investing any time into asm.js right now. We'd prefer that developers adopt WebAssembly instead, and then they'll get better performance automatically.
