I am on Firefox 91.0.1 (64-bit) on Debian 11. As the example screenshot shows, UI on many webpages looks wierd and inconsistent. I also use Firefox on my work computer, which is on Windows 10 and has no such issues. So, I think this is because of some dependency issues with my Debian machine. How do I fix this?

Hello,

I'm using firefox-dev under linux debian buster and would like to keep it as my default browser and even more after all those recent articles in media where they say firefox is loosing its users.

I received the newletter from netflix and I tried to watch a trailer (https://www.netflix.com/watch/81387952?trkid=13710079&MSG_TITLE=81387952&lnktrk=EMP&g=79ECBFC7B02B1269F43D15B11C9BA9F56455502C&lkid=TRAILER_CTA) but even after i clicked on accept drm, the video was stuck nothing happened I just saw one single fixed picture of the movie.

Later, I was on facebook, trying to watch a video (https://www.facebook.com/demotivateur/videos/5009752875718446) and the same here without any DRM...

For both of the cases I opened chrome pasted the url and video played very well.

Is there something to tweak to make it work ? Is it because I'm under debian ?

I don't want friends to switch to chrome but I understand them sometimes.

Kr,

Eric

Hello,

I just upgraded to firefox 92. When I right click on a string I wrote such as : "zaiuryezoyhdsofh" with spell check enabled, Firefox hangs for minutes and my CPU is 100%. It happens only on a string and on every websites, even google search.

I'm able to reproduce in safe mode, but FF doesn't want to crash so no report.

System : Debian Buster 10.

Hi. I'm having some issues to render CSS effects and videos after last update (version 91.4.1esr). Before that update everything was pretty smooth, but since the update the browser is getting very slow to render "everything that moves" on the screen. The movements are poor on CSS or videos, its like it was exceeding in any video/memory resources, get very slow and nothing smooth.

My system: - Linux Debian 11 (fully updated) 64bits; - Processor: Xeon 2670-v3; - Ram: 32GB; - Graphics: Quadro 2000; - Graphics Driver: official Nvidia 390.144 x86 with 32bits support downloaded by Nvidia's site.

Any hints on how can I solve this?

Very similar to posts in previous years that are archived and largely unanswered or not up-to-date.

I opened up my a Firefox session to find out I was logged out of sync and when I logged back in all my passwords where erased.

This has been stable for the last 10 months and Firefox has provided a reliable password archive with nice syncing features. However, this is a deal breaker, since I cannot loose the login credentials randomly.

No updates. No conscious logging out. No disregarding warnings etc.

Anyway to revert or retrieve?

Hello, First let me thank Mozilla again for a great experience. I've been using Firefox as my main browser for many years and since some time I also started supporting Mozilla financially with whatever little I can with recurring payments. To the problem: since some time patch / commit view on HitHub with Firefox is broken. I guess many @mozilla have github accounts so you can open and read https://support.github.com/ticket/1318472 but to summarise: my first entry there was: ``` When viewing Linux kernel style Pull Requests on GitHub, using Firefox, TABs are displayed as 4 spaces, which is confusing, since the default is 8 spaces, which is also what is displayed in chrome and chromium. E.g. https://github.com/thesofproject/sof/pull/4747/commits/e9cc9312841a9329797b0b676335c8cb1a0dc779 ``` then a screenshot (attached) and a clarification to it: ``` As you can see there the patch area between lines 238 and 245 is wrongly indented by 4 spaces, whereas areas above and below are correctly indented by 8 spaces. ``` Then more: ``` No, space isn't used for indentation in that code. They can download raw code and verify, I'm sure they know how to do that. Why don't they just reproduce that themselves? Start Firefox, navigate to any PR commit like https://github.com/thesofproject/sof/pull/4884/commits/b19a64df2c2fcd63d7407ef500fd3312287c8995 and click arrows above and below the diff to display surrounding code. Then navigate to or download the raw patch https://github.com/thesofproject/sof/commit/b19a64df2c2fcd63d7407ef500fd3312287c8995.patch to see TABs used everywhere. Should be very easy to verify. ``` and their last reply was ``` From a technical standpoint this is not a regression. It's a problem with the way firefox interprets the combination of the tab-size css and the particular markdown we use for our diffs.

After reviewing the Issue in more detail there it has not been prioritized and will most likely not be addressed in the near future. ``` This is a deal-breaker for me. I spend hours daily reviewing GitHub pull requests. And I'd really not want to use a different browser just because of this... Please help! Thanks Guennadi

Hello. I want to report a performance issue (slowness) caused by the overexcesive virtual memory usage by Firefox sub-processess.

State description

After runing Firefox, I observed in the htop the process of Firefox (and it's sub-processes) and compared it with the about:processes

I had discovered that main Firefox process opens many sub-processess that aren't even used (they does not appear on the mentioned above "about" page).

Additionally, in some mement, at latest one of the created sub-process start to use 28.6 GB of virtual memory, like each of the created by it sub-process. This causes quite big loose of stability of the browser and even system

I am running Firefox Browser 97.01 (64bit) Mozilla Firefox Snap for Ubuntu canonical 002-1.0 on Raspberry Pi Debian GNU/Linux 11 (bullseye) version ID 11.

I am trying to stream various TV services like CTV.ca, CBC.ca, etc. I am getting the following error message: This video file cannot be played.(Error Code: 102630)

I have tried the solutions recommended in the forum with no luck.

What am I missing?

Regards.

Using Firefox 100.0.1. Debian Linux. Dell 1525 with 4G ram.

When playing a certain mp3 file in the browser, if I use the arrow keys, or the mouse, to skip forward or back, there is no response, but the audio stops playing for a period of time, then, finally it starts playing again at the spot it was before.

This does not happen with this file in Chrome, or in VLC. Also, with other mp3s it does not happen in Firefox.

I finally got it to work by converting the file to ogg vorbis, but this is not something I want to make a practice of..

I imported the file back into Audacity, and re-exported it as an mp3. Same result.

Weird... Any ideas?

Thanks,

I use Firefox on Linux Debian 11 (Bullseye). After a recent automatic update to Firefox 91.10.0esr, some websites will not load (just sit with a blank page, showing flicking loading symbol). Examples are ocado.com and abelandcole.co.uk. I have tried all the usual things to fix, including, switching off VPN, clearing cookies and caches, running in safe mode, all with no success. Both sites run fine in Vivaldi and Brave. I have eventually got the pages to load by disabling IPv6 in Firefox. Clearly there is a problem with 91.10.0esr. I'm not sure whether the workaround of disabling IPv6 might cause other problems or weaken security or privacy?

Hi!, recently i have been having this browsing problem whenever I open the news website at https://www.cgtn.com/channel/documentary. The site wont load and error is shown- "cannot load M3U8:levelLoadTimeOut". Have tried numerous times but failed to load. However other web sites have no problem and prior to this I am able to surf at all times. What must I do to get back the browsing? Any help is appreciated. Thanks

installed debian sid on userland app. installed firefox. when i launch firefox, it just shows "gah: your tab just crashed". entering duckduckgo.com and press enter, it shows same error message. disabling hardware acceleration has no effect. is there any way to make it usable on my device?

I need some things to look at. Debian 11.4 Bullseye 16 CPU 72GB I just got the Mate desktop working. Thought I'd find a cool wallpaper. Site said it needed to load an extension. I tried to escape but now my firefox fails to load even in troubleshoot mode. It builds the window frame I can almost touch the menu and gone.

Checked .mozilla/firefox/Crash Reports/ and it's empty checked .mozilla/extensions/ and it's emtpy Got an install time InstallTime20220718130424

as I click on Firefox Icon in menu the screen pops alert that says: "Firefox closed unexpectedly while starting....try to resolve the problem in troubleshooting in SafeMode."

tailing syslog: tail -f /var/log/syslog gives this clue: oom-kill:constraint=CONTRAINT_NONE, task=firefox-esr total-vm:672432kb Kernel Out Of Memory killed process pgtables:840kb oom-score_addj:0

I can add more detail if I know where to look. OOM with 72GB ?

I'm running Debian Stretch and the packaged version of Firefox (91) runs fine but seems a bit dated. I installed ver. 104 manually and everything is fine except that there is no audio. I changed the setup Privacy and Security Autoplay to 'Allow Audio and Video' -- no audio. I've restarted in troubleshoot mode -- no audio. Other browsers, including ver. 91 of Firefox have no trouble with audio. Any ideas? On quitting I get these messages:

Every time I login to my desktop it tries to restore Firefox and in turn Firefox tries to restore it's session, however all I get is a mess of graphical glitches, the interface doesn't even load, I get a window border and usually a copy of the KDE splash screen. I then have to kill the process, which of course means it looses my session so when I re-open it I get nothing, all my open tabs are gone and there is no restore session option.

Further, it can't even play streaming videos properly anymore. After one or two episodes of a TV show its lagging sometimes by minutes, eaten gigs of ram and the video often gets stuck, the audio helpfully carries on with a frame of video from about 5 minutes ago. This is not an exaggeration, I had a YouTube video where it changed to a graph with a voice over, after 5 minutes I started to notice the voice over was talking about things not on that graph and sure enough the video had frozen. Its an i9 10850K with 32GB of RAM. The previous version of Firefox didn't mind restoring a session with over 350 tabs and plenty were videos, this one can't handle 2 when one is a video without freezing or locking up the whole browser.

No other apps/ programs on this PC are having any issues, it is only happening in Firefox, I can for example open a media player and play a video just fine while the video is stuck in the browser or it has the graphic glitches. I also tried opening another instance of Firefox while it had the graphical issue, the new instance started and created a new entry on the task bar, but switching to it gave the same display as the broken one, I can't tell you what tabs either had open as nothing inside the window was rendered at all, not even the menu bar which I set to always being visible.

Hi I am using Firefox on Debian 10, and it just plays audio to the pulseaudio server to the right channel. No idea why. Other applications are serving audio in stereo. Any other reports of this or fix?

FireFox 102.6.0esr on Debian 11 with a 5.10.0-20-amd64 kernel. (http://security.debian.org/debian-security stable-security/main amd64 firefox-esr amd64 102.6.0esr-1~deb11u1 )

My problem initially started out on a profile migrated from Windows (with some extensions installed), but Ive reproduced from a brand-new profile. Similar to https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can

Although the problem is sporadic, it occurs more way frequently than I would like. I have done quite a bit of troubleshooting with different profiles, used the --profile flag, sometimes --safe-mode, sometimes called around strace -- the results are pretty much the same.

Launch FF (as a new profile), and it will display the two tabs:

• tab 1: "FireFox starts here" image of Soraya Osorio.
• tab 2: https://www.mozilla.org/en-US/privacy/firefox/

Sometimes I am able to load in an additional website (which is short-lived), but ultimately traffic peters out and tabs are just spinning endlessly. No network timeouts. Firefox's just waiting on ... something.

Other times, when loading the profile with extensions enabled (NoScript, Multi-Containers, etc), clicking on a extension's drop-down menu (eg: Multi-Containers) it's not a full rendered drop-down but instead a thin (~2px) vertical line.

Errors from commandline:

• Missing chrome or resource URL: resource://gre/modules/UpdateListener.jsm
• Missing chrome or resource URL: resource://gre/modules/UpdateListener.sys.mjs

(The clean up of FireFox on normal quit can take up to 30 seconds)

When wrapped in strace I see ridiculous amounts of

• recvmsg(4, {msg_namelen=0}, 0) = -1 EAGAIN (Resource temporarily unavailable)

interspersed with

• recvmsg(4, {msg_name=NULL, msg_namelen=0, msg_iov=[{iov_base="\16\0y\n+\0`\1\0\0>\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\

0\0\0\0\1\2z\n\0\0\0\0,\0`\1\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0\0", iov_len=4096}], msg_iovlen=1, msg_controllen=0, msg_flags=0},

0) = 64

Im not sure why this occurs with only FireFox. Ive ran instances SeaMonkey, Pale Moon, WaterFox, Epiphany, Google Chrome, Brave and Vivaldi without seeing these issues.

I highly suspect there's a conflict with something else I run. Already disabled fail2ban and apparmor. Are there any system calls from the strace that I should look for?

I am running Firefox-112.0(64bit) on Debian Bullseye. When I pend Firefox I am presented with a blank page rather that my normal sign in page.

Opening a terminal window and starting Firefox with /opt/firefox/firefox generates the following errors:

comp@AbNormal:~$ /opt/firefox/firefox [GFX1-]: glxtest: VA-API test failed: no supported VAAPI profile found. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. ATTENTION: default value of option mesa_glthread overridden by environment. [ERROR glean_core] Error setting metrics feature config: Json(Error("EOF while parsing a value", line: 1, column: 0))

If I enter a URL the page opens and is usable.

How can this problem be fixed?

Thanks in advance.
