User Agent: Mozilla/5.0 (X11; Linux x86_64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/74.0.3729.169 Safari/537.36

Steps to reproduce:

Trying to open any website does not work, it is being loaded and after many many minutes, it times out with "corrupted content error"

I attach a pcap file where I took a complete packet capture of my wlan interface. No other application (like another browser, or email client, etc.) was running. I then started firefox by typing "firefox www.wikipedia.org" into a terminal.

This issue surfaced one or two days ago.

I am running Ubuntu 19.04, I upgrade packages every day. The problem probably surfaced due to an upgrade one or two days ago.

Description: Safe and easy web browser from Mozilla
Firefox delivers safe, easy web browsing. A familiar user interface,
enhanced security features including protection from online identity theft,
and integrated search let you get the most out of the web.

Actual results:

The website is tried to be loading ("Waiting for ....") but nothing is happening.

After a long while, the "corrupted content error" page is shown.

Further information: I disabled all add-ons prior to the test (taking a packet capture, then "firefox www.wikipedia.org".)

Please let me know how I can assist further.

According to /var/log/apt/history.log, firefox and firefox-locale-en was upgraded yesterday, on 2019-05-22:

Start-Date: 2019-05-22  06:04:51
Commandline: /usr/bin/unattended-upgrade
Upgrade: firefox:amd64 (66.0.5+build1-0ubuntu0.19.04.1, 67.0+build2-0ubuntu0.19.04.1)

End-Date: 2019-05-22  06:05:01

This may be a likely culprit.

I need to see how I can downgrade to the previous version of the package. I will report back once I figured that out (and find the time for it.)

[Tracking Requested - why for this release]:

this issue also got reported on a couple of support channels with references to a "seccomp sandbox violation":

Confirmed: downgrading the Ubuntu firefox package to 66.0.3+build1-0ubuntu1 made firefox work again.

Tracking, the other reports all seem to hint at a user profile corruption (I am on Ubuntu 19.04 myself and didn't experience this issue btw).

tracking-firefox67: ? → +

I think we are missing a piece of the puzzle here.
The upgrade from 66 to 67 works for me as well on Ubuntu 16.04 and ubuntu 18.04, both with canonical and Mozilla builds.

I can't really wrap my head what could generate this kind of behavior from the profiles point of view. Maybe Dave could get more info out of poc file.

What would probably would be helpful is if trittweiler@gmail could assist a bit more into building up a scenario that we can use reproduce this behavior reliably:

  1. Can you clarify if the profile used after update is the same profile than the one before the update. (about:profiles)
  2. Confirm that the symlink is the default one. If there's anything custom about the symlink done, it would probably be good to know.
  3. Can the same scenario be confirmed with the Firefox updater or just with package updating?
  4. Can the same scenario be confirmed using a Mozilla tar.gz ?
Severity: normal → major
Component: Untriaged → Startup and Profile System
Flags: needinfo?(trittweiler)
Product: Firefox → Toolkit

Profile corruption doesn't necessarily indicate that this is profile switching related. More likely there is a bad pref or something in the profile that doesn't work. Some of the reports indicate that clearing the caches help and we do store some ssl related info in there and have seen issues with that before.

I wonder if Dana has thoughts here.

Can you run with the environment variable MOZ_LOG set to pipnss:4,certverifier:5 and upload the output?

Re. 1) and 2):

Could you provide more information about which paths you want me to check the symlinks for, please?
I certainly have no recollection of having ever done anything in ~/.mozilla or ~/.cache/mozilla

Re 3)

My assumption is that Firefox' native updater is disabled on Ubuntu, could that be? I have never been prompted by it at least.

Re 4)

I downloaded firefox-67.0.tar.bz2 from mozilla.org, unpacked the tarball, and run ./firefox from the extracted directory. After startup, a dialog popped up saying that this invocation will NOT use my profile from other installations of firefox.

Firefox from firefox-67.0.tar.bz2 is working fine under those circumstances.

Thanks! Doesn't look like a certificate or TLS problem, then, as connections appear to be succeeding.

Dave, any other ideas for possible causes, not that Dana has ruled out TLS certificate issues?

Timing out while loading seems to suggest that this could be a networking issue.

It is important to note that with CVE-2019-11707, resolving this issue actually becomes really important to those stuck with the Firefox 66.

Starting firefox in safe mode (firefox -safe-mode) resolves the issue. So it seems like it is indeed one of the plug-ins which is at fault.

I will see which one it is.

HOWEVER:

Disabling the add-ons manually under "Add-Ons (Ctrl+Shift+A)" in the "Open Menu" does NOT help, the issue still persists.

To be precise: I disabled the add-ons on the old version, upgrading to 67, invoking firefox with "firefox www.wikipedia.org"

The priority flag is not set for this bug.
:michal, could you have a look please?

For more information, please visit auto_nag documentation.

Flags: needinfo?(michal.novotny)

Given that we will ship 68 in 2 weeks and that this is still at the investigation phase, I am marking it as wontfix for 67.

status-firefox67: affected → wontfix
status-firefox68: ? → affected
status-firefox69: ? → affected

Re 4)

I downloaded firefox-67.0.tar.bz2 from mozilla.org, unpacked the tarball, and run ./firefox from the extracted directory. After startup, a dialog popped up saying that this invocation will NOT use my profile from other installations of firefox.

Firefox from firefox-67.0.tar.bz2 is working fine under those circumstances.

Could you please check if the official version works fine with your current profile? It should be possible to select the profile if you run:
$ ./firefox --no-remote -P

Could you please also check whether ubuntu version works fine with a clean profile?

Flags: needinfo?(trittweiler)

Hi Michal,

I tested a clean profile on the upgraded ubuntu version, and that worked successfully:

  1. I ran firefox -ProfileManager www.wikipedia.org
  2. I created a new profile, with the name "clean_profile"
  3. selected "clean_profile", and clicked on "Start Firefox"

And firefox launched and could successfully render wikipedia.org.

I am going to test firefox 67 vanilla under my suspicious profile next.

I ran ./firefox --no-remote -P from the official firefox-67.0.tar.bz2 tarball that I had downloaded end of may, selected the "default" profile (the "default-release" was pre-selected), launched firefox, and tried to open www.wikipedia.org.

It did NOT work.

Same buggy behaviour of endlessly retrieving the website.

Would it be helpful to upload my profile? Which directory would that be?

Would it contain sensitive information? Passwords? If yes, what is the procedure to remove sensitive information?

Hi, can you please provide a new log with added one more module to the MOZ_LOG variable: "nsChannelClassifier:5". Thanks!

Would it be helpful to upload my profile? Which directory would that be?

The profile directory is /home/trittweiler/.mozilla/firefox/4c4hf078.default

Would it contain sensitive information? Passwords? If yes, what is the procedure to remove sensitive information?

I recommend to back the profile up first.

Hi, can you please provide a new log with added one more module to the MOZ_LOG variable: "nsChannelClassifier:5". Thanks!

Done. Please see "firefox_log_nsChannelClassifier.tbz"

Curiously, I could NOT reproduce the problem with mozregression at all.

I have tried the following arguments to --bad:

--bad 67
--bad 67.0.4
--bad 68

In each case, I could successfully retrieve and render web pages. (I did pass the --profile=.... flag, and verified that the "default" profile is in use via the "about:profiles" page.)

This is a critical regression (coming from likely duplicate bug 1561251);
(RE the wontfix tag for v67, IMO this should be a blocker; however I am unfamiliar with the release cycles and how bugs get scoped and/or back-merged, so hopefully that is the right decision ;o)

Let me know if we need additional debug information; (looks like @mayhemer has a lead with the URL classifier thread.

Dimi, do you have time to take a look?

Hi trittweiler,
I also need your help provide a new log with only the following MOZ_LOG set:
"UrlClassifierDbService:5,nsChannelClassifier:5,UrlClassifierProtocolParser:5,UrlClassifierStreamUpdater:5,UrlClassifierPrefixSet:5"

It will be also very helpful if you can find the 'safebrowsing' folder in the profile and upload it(or just upload the entire folder)
Thank you!

@dimi,

Here's my version of the initial MOZ_LOG request and the URL classifier debug logs. (attaching)

Unfortunately, I never see a "safebrowsing" directory in my profile (despite the fact I see it noted in the log output of the classifier ...)

fermulator@fermmy-notebook:/.mozilla/firefox/gx3w7gfd.default-1561215211227$ find . | grep safe
fermulator@fermmy-notebook:/.mozilla/firefox/gx3w7gfd.default-1561215211227$ cd safebrowsing
bash: cd: safebrowsing: No such file or directory

Flags: needinfo?(mozilla-bugzilla)

This caught my eye

[Parent 14332: Main Thread]: D/UrlClassifierStreamUpdater nsUrlClassifierStreamUpdater::UpdateError [this=7fe85c195e20]

and,

[Parent 14332: URL Classifier]: D/UrlClassifierDbService Notifying error: NS_ERROR_FAILURE (2147500037)

and,

[Parent 14332: Main Thread]: I/nsChannelClassifier FeatureData::InitializeList got an unexpected error (rv=NS_OK)

Otherwise we see this often

[Parent 14332: URL Classifier]: D/UrlClassifierDbService Failed to read the value.

(obviously I don't know the code base, so whether or not these errors/failures are relevant I am not sure)

Hi fermulator,
This is really helpful! thanks.
I found a issue that we don't handle the corrupted safebrowsing database very well, i will provide a patch to fix the error handling.
I'll then investigate why the database was corrupted in the first place.

Firefox cannot open any URL when Safe Browsing database is corrupted.
This is because when Necko asks URL Classifier to classify an URL, it
first suspends the channel, and then wait for a callback to see if the
channel should be canceled or resumed.

In this bug, DoLocalLookup returns an error because Safe Browsing is not
able to read its database(database is corrupted), but we don't call the
callback to resume loading channel, so users cannot load any website.

This patch adds a scope exit handler to make sure the callback will
always be invoked.

Given that it is very close to release date and this could be recovered through Safe Browsing update.
I'll not uplift to release.

What exactly is this assumption based on? Afaik we don't even know yet what corrupted the database in the first place, meaning it could happen again even after recovery, right?

I should comment more detail, sorry for not doing this in the first place
Base on the description and log, I think this only occured while upgrading Firefox because of the recent changes in Safe Browsing(Bug 1353956 did modify the format of database). But I am not yet clear why this happened.

I simulated the corrupted database(based on the log) by manually modify it to figure out how to fix it and to test if it can be recovered.

@dimi @dlee, that assumption is false.

In fact my browser is in a state of constant "safebrowsing" corruption (whatever that means). See bug 1561251.
Any earlier uplift would be appreciated as I prefer to remain on a stable branch. On the system I'm running, this is the version I have atm

Hi fermulator,
Thank you for the info. Can you help upload the corrupted database?
You can find the directory containing it by opening about:profile, find the profile you are using and see if there is a "safebrowsing" directory under the "Local Directory". And if there is also any other directory whose name begins with "safebrowsing-"(for example, "safebrowsing-backup"), please also upload it, thanks!

Ah, I see. I might know the reason that why you are in a state of constant "safebrowsing" corruption.
Safebrowsing database has multiple tables, and in the case of multiple tables are corrupted, a safebrowsing update only resets one corrupted table (Because when it finds an error, it stops the update and resets the table, it doesn't examine the remaining tables).

But for this bug, as long as there is still one corrupted database, the bug occurs. So if there are 5 bad tables, it needs 5 safebrowsing updates to recover... And this feels like a constant failure in a lot of cases. I filed another Bug 1564032 to improve this.

Thanks; I've shifted this discussion into bug 1561251.

ESR Uplift Approval Request

  • If this is not a sec:{high,crit} bug, please state case for ESR consideration: Corrupted Safe Browsing database may cause users cannot open any web page.
    Corrupted database may happen while upgrading Firefox from 66(or versions before 66) to 67(or 68) on Ubuntu.
  • User impact if declined: Users cannot open any web page
  • Fix Landed on Version: 69
  • Risk to taking this patch: Low
  • Why is the change risky/not risky? (and alternatives if risky): This patch doesn't change any behavior for the normal workflow. It only affect the cases when SafeBrowsing detects an error(this doesn't occur very often). And we don't do complex error handling when an error occurs, we just skip the lookup.
  • String or UUID changes made by this patch: None
