User Agent: Mozilla/5.0 (Windows NT 10.0; Win64; x64; rv:65.0) Gecko/20100101 Firefox/65.0
Steps to reproduce:
Basically play any video on youtube by clicking open in new tab.
Actual results:
firefox freezes/hangs for a few seconds. While this is happening, i cant click on other tabs or close or minimize firefox. I had task manager running in background to see if my cpu or hdd or ram reaches 100% resulting in freezing but i wasn't the case. everything was normal. I have also recorded a video of it. here is the link - https://youtu.be/gPOzcZWT5SQ
i don't
t know if you can make it out from the video, but the mouse movement that you see in between the tabs, its me trying to switch tabs but since firefox is frozen, it wouldn't let me do it.
i am on the latest version of firefox quantum 65.0.2
my amd rx 470 gpu driver version is 19.2.2
my windows 10 version is 1809 build 17763.316
this started happening like a week ago. I have not made any changes to my add ons.
i was using the following addons before the issue started occuring and i am still using these add ons
alternate player for twitch.tv
hoxx vpn
idm module
popup blocker ultimate
ublock origin
i tried googling to find anything related to my problem. there were posts regarding firefox freezing but none pertaining to my specific case so i decided to care a bug report here.
Expected results:
Firefox should not have frozen. It should have seamlessly played the video.

Had the same problem with Version 65.0.2 (automatically updated to recently). Windows 8.1 here. Terrible hang ups opening Youtube videos. Would freeze partway opening resulting in just a black box appearing with no video playing in it and very slow result to closing the tab, greater than 30 secs or so.
I have downgraded Firefox back to version 64.0.2 (64Bit). Problem disappears. Youtube (even using multi tabs with several videos all playing at once) now plays fine with no hang ups at all. Tab instantly shuts when X clicked. I tried disabling graphic acceleration etc. Didn't do anything.
I might add Opera / Chrome has no problems playing the same content.

Windows 8.1 on the beta channel. Latest Nvidia drivers for GTX 980.
I experience the same issue as depicted in the video linked in comment #0. The hangup occurs regardless of newtab or not as well as on embedded youtube-videos from reddit and such.
The issue has been going on and off for maybe a month. I've tried a new whole new profile, as well as turning off h/w accel but to no avail.

This looks like something that happened in between 64.0.2 and 65.0.2, but maybe it's between 65.0 and 65.0.2 (based on the dates of the reports). I don't see anything obvious in the log, and I can reproduce on my windows machine here, it must be OS and HW dependant.
I can't repro on my windows machine. It would be amazing to find a regression range here. We have a video that explains the process here: https://mozilla.github.io/mozregression/quickstart.html. This is available as a command line program or with a graphical user interface.
This will download a few Firefox in short succession in between two releases (like 64 and 65 here), and will find the problematic code changes.
This sounds like a main thread hang. We don't do much on the main thread for media, but there is a dispatch sync on windows, but I can't find it. jya, do you know where it is, and/or whether it was added in the suspected range?
I've attempted to locate the regression with the tool but with no success (It simply doesn't occur). I've completely purged and reinstalled Firefox but the issue remains. I fired up a VM and tried to replicate the issue but without success.
I used the Gecko Profiler to record the following if it maybe tells something;
https://profiler.firefox.com/public/4c4941c047da08495cd0e3cc2ce3f2ef43fb8153/
This is pressing a random video from youtube.com, and shows the freeze while rendering and a smaller freeze when initializing playback.
For now I've started using Nightly for now since it works fine.

Very cool that you were able to do this, Arvid, we have our smoking gun right there where there is a pinkish bar that says, on hover "5009ms event processing delay". It's caused by bool mozilla::RDDProcessManager::EnsureRDDReady, so I'm sending that over to Michael.
It happens twice, as you note, one at the beginning of your recording session, and one a bit later a bit before doing lots of network requests, presumably because we're about to start playback.
Again, thank you very much, this was extremely useful information!
Michael, it seems that we're synchronously waiting for an asynchronous operation on the main thread, this is not something we should be doing, can we have a look at this quickly?

I confirm due to video that demonstrates the error and the profile that reveals the issue. I see in the content process that the PContent::MSG_LaunchRDDProcess takes 5000, 15007ms and 5001ms.
It is also reported that the error does not repro in Nightly. I hope we have fixed it in between.

I looked at this briefly in the past, but was unable to make async launch work. I don't understand enough about how the actual process launch mechanics work to make a quick fix. I would be happy to work with someone on converting to this to async so I can learn more about it.

PContent::MSG_LaunchRDDProcesstakes 5000, 15007ms and 5001ms.
Those values are… interesting.
It would help to add ,IOThread,Launch to the end of the “custom threads by name” list in the profiler (the dropdown from the toolbar button), to see what's going on with the process launch itself.
We have telemetry for process launch times (just the launch itself, not waiting for the process to start and connect back), and multi-second times are uncommon, but there is a very small peak in the bucket containing 5000ms.

I have run the mozregression (Windows GUI) to its end. Very interesting tool to run. Thanks for the experience. With some of the versions, Youtube would run fine, others stuck. Having never done this before, does it automatically load it to you? If not, I have saved the entire log anyway.

That regression makes sense since before that we were launching the RDD process at startup. Now it is launched only when needed, meaning when an AV1 decoder is going to be used.

YouTube now appears to be using AV1 for the low resolutions. This is likely what make this bug only appear now.

from the looks of it, i guess you guys found the issue?
i tried doing the regression thing. I set last good build as 64 and last bad build as 65 and tested upto 8 builds but the issue did not occur. Youtube worked fine. It never froze when i did the 'open in new tab' for any video. I stopped testing builds after this.
If you still need any data, please let me know. I'd be happy to help.
On side note : i dont know how this needinfo request works in here. so please ignore any needinfo request you see from my side.

We didn't have AV1 support until 65. And YouTube wasn't serving AV1 then (I only realised they were using AV1 by default today).
For now, I've contacted YouTube asking them to stop serving us AV1 on Firefox 65 and 66.

For now I've started using Nightly for now since it works fine.
Do we have any idea why this would work on Nightly but not Beta 66? The only related bug I know of is bug 1487287, but that just changes the thread where we do CreateProcess (and the sandbox setup); everything else that's waiting for the launch to finish would still be waiting. But if there's third-party software injecting DLLs into Firefox that's causing this problem, and it's not detecting Nightly as something to target, that could explain it.
It would be helpful if someone could reproduce this while profiling with IOThread and Launch added to the thread filter as mentioned in comment #11, to see where we're blocked. There's an AV1 test page that should work even while the YouTube change is rolled back.

Yeah I'm also wondering if some security or anti virus software or something like that slows down process creation. For the folks who experience this problem: do you run any anti virus software on you systems?

I had similar thoughts and played around with disabling Windows autostarts and renaming the Firefox main executable to (maybe) exclude such issues earlier.

Indeed the freeze showed again when I visited the demo, where as Youtube now seems to work. Again the freeze both while painting and starting playback.
I attached the json since the upload thing didn't work for some reason.

I do run antivirus but having updated FF back to 65.0.2, YouTube videos now play without any problems - presumably because of the fix applied by YT.
Playing the AV1 test video - I don't know if it is normal for the clip to change resolution and download speed on the fly? E.g was playing quite well at 720p@800kbps to then go down to a new res of (variable)p@100kbps resulting in a hang up for a good couple of seconds each time it occurred, even though the buffer is showing 15% full and climbing! FF itself hangs, stutters, at that point and will not let me change tabs until it is done.

Yes YouTube works fine again, because they no longer serve AV1 videos to Firefox. So you get VP9 videos instead, and VP9 decoding doesn't take the same path in Firefox.

The profile in comment #23 shows the IPC I/O thread completely idle while the main thread is waiting for the process to connect back (and this is 66, so launch happens entirely on that thread). And the timeout is exactly 5000 ms, which I didn't notice until now (cf. 30s for GMP), so either the process is somehow taking longer than that to reach the point early in startup where IPC is initialized, or else it's crashing (or deadlocking) before that point.

Jed, any thoughts on how we might tell whether the process is crashing or just taking super long? I thought 5s was a generous launch timeout. Surely we wouldn't expect processes launches to take longer than that often would we?

I don't know much about how Windows handles this kind of thing, so I asked on IRC #runtime; jimm mentioned that the event viewer should have crash information if there was a crash.
In principle IPC could be doing more here to report what the OS can tell us about child process status, but it's not, and that won't be simple to fix.
As for whether 5s is enough, I don't know that we have telemetry about this on Windows, but we effectively do on Mac (see the parenthetical in bug 1536683 comment #0), where the 99th percentile on beta is about 2.6s.
But I can think of a simple way to test this: change media.rdd-process.startup_timeout_ms to 30000, try to repro, and see what happens.

I changed the value and reproduced the freeze, this time taking 30000ms instead of 5000. The event viewer showed a Application Hang, but there's no dump or anything i perceive as useful.

Anthony Jones mentioned that this sounds similar to bug 1515088, in which case we'd apparently need exactly the same version of Windows (the specific build, not just Win10 vs. Win8 etc.) to try to reproduce this.
Another thing that could be tested is to temporarily turn off the RDD sandbox by setting the MOZ_DISABLE_RDD_SANDBOX environment variable.

I don't think anyone's reported this on 67 yet, and there are reports (comment #7, comment #33) that this doesn't reproduce on the 67 branch, both as late Nightly and early Beta. So it's possible that it was fixed by something that landed in the 67 cycle but wasn't uplifted to 66. Note that YouTube will still serve AV1 to 67 and up (comment #20, also verified experimentally).
It would be interesting to see if this is reliably broken on an early 67 Nightly (like 2019-02-01); if so, mozregression should be able to find where it was fixed.

Firefox was upgraded automatically today to 66.0.1 (64-bit). I have run the AV1 Test video mentioned in comment #21 and that still stutters in Ver 66. I have also downloaded Ver. 67.0b4 (64-bit) and Nightly Ver 68.0a1 (2019-03-23) (64-bit) and have run the AV1Test Video in both (several times) and the video runs as expected. Very smooth.

It also moves the MITIGATION_DYNAMIC_CODE_DISABLE to be enabled after start-up.
This is required because the hooks to fake the user32 and gdi32 initialization

That does seem odd, my guess would be that it was the other things that were part of the same changeset. There is a pref to turn off the win32k lockdown (set security.sandbox.rdd.win32k-disable to false), so we could prove if it were the lockdown.

security.sandbox.rdd.win32k-disable doesn't appear in about:config in FF 66.0.1 (64-bit)
security.sandbox.rdd.win32k-disable appears in FF 67.0b4 and whether the pref is set false or true, the test video plays seamlessly.
With the video playing in the background on FF66, there are definite pauses switching between tabs and I am seeing the same as I type this on FF66. Hopefully it is fixed in FF67 as that seems to play fine, switching tabs occur seamlessly with no pauses etc.

Also, if you're up for a small challenge, we'd love to get a profiler run from you on the system that experiences the issue.
Think I've done it correctly, if not, let me know.
System Win 8.1, Intel I7 4790K 16Gb Memory, GPU Radeon RX580 8Gb.
Firefox 66.0.1 With all Add Ons disabled (except Gecko)
Av1 Test Video used. Video only playing with no other inputs or mouse movement etc.
Gecko Profile URL: http://bit.ly/2HTQUCB

Basically the same as comment #30: 10ms in NtCreateUserProcess, which is reasonable, then blocking for the entire 5 second timeout waiting for the process to connect to the named pipe.

I can't reproduce this issue, but my guess is that it was the removal of the COM initialization as part of bug 1511438 that fixed this.
The COM initialization wasn't needed for AV1, but it is for other decoders and in bug 1535704 we're investigating how we get that to work with the sandbox.

OK. Can we close this bug since bug 1511438 is fixed in 67, and there is a followup filed for the remaining issues in bug 1535704? Or, is there something left to do here?

I think that's reasonable since Bug 1535704 exists.

Looks to me like there isn't any action to be taken here any more. So I think we can close. There is always the option to re-open.
