Firefox Community Forum

For the last 2 weeks I started having problems with Firefox working consistently. Sometimes only tabs crash, sometimes Firefox crashes. It is not tied to any actions, a tab can crash even if you don't perform any actions in the browser. I have tried clean install on Fedora and Vanilla OS, native and Flatpak packages. The result is always the same - tabs or Firefox crashes every few minutes.

Hi, I'm using Linux Mint 22, Firefox 129.0 (64-bit). Browser is hanging after approximately 4 hours. Not sure if this is a Firefox issue, but this is where I'm starting the troubleshooting process. My suspects are (1) the browser, (2) NVIDIA drivers (3) the new Linux Mint kernel or possibly (4) a mix of the above. This was a fresh install with default options on (Wilma). Using the latest graphics drivers for GeForceRTX 2060, driver version 555.58.02, went down to native drivers, no change. Honestly, this one has me baffled. Been troubleshooting this for 3 days. It feels like a memory leak. Nothing on the crash reports. First, browser will hang, then mouse and keyboard. Hard reboot is the only option. Any help would be appreciated.

Problem loading images on Home Depot website. It happens when you want detailed images of a product. This is not just one linux distribution. Its many of them. In the case of Ubuntu same problem with Snap version. Whether .deb or Snap doesn't matter.

I've got a test machine with 10 ssd's in it. I switched over to Ubuntu 24.04 that I installed/configured several months ago. Before updating I checked Firefox. It was version 125. No problems with Home Depot. Updated system. Firefox updated to 128.0. Home Depot wouldn't load images anymore. Did all the usual stuff like disabling a couple of extensions. There are only two. Adblock Plus and Weather. Other than that no changes to Firefox that would be a problem.

I've got Google Chrome installed on these machines too. Home Depot no problem. Images of product load and display fine.

I don't order much on Home Depot so using Google Chrome is not a problem for me. But it is annoying and I know I'm not the only one. Seen it posted in a few forums with no resolution. Also, I have not had any problems with Amazon or Lowes website.They are similar in that they display detailed images of each product. I'm not implying that Home Depot is the only one. Just that its the only one I have discovered. If I recall correctly 127.x may have been where it started. The general images of many products don't seem to be a problem.

Thanks, Gerald

Firefox 129.0.2 (64-bit) Mozilla Firefox Snap for Ubuntu canonical-002 - 1.0

Running on kubuntu Linux 24.04, kernel version 6.8.0-41-generic (64-bit) KDE Plasma Version 5.27.11 Qt Version 5.15.13

I've posted a description of my problem on the kubuntu forums: https://www.kubuntuforums.net/forum/newbie-support/help-the-new-guy/681835-firefox-eating-up-a-lot-of-cpu

Here is a synopsis of my posts on that thread to distill the most noteworthy symptoms:

I have snap Firefox installed.

$ snap list Name Version Rev Tracking Publisher Notes bare 1.0 5 latest/stable canonical✓ base core22 20240731 1564 latest/stable canonical✓ base firefox 129.0.2-1 4793 latest/stable mozilla✓ - firmware-updater 0+git.5007558 127 latest/stable/… canonical✓ - gnome-42-2204 0+git.510a601 176 latest/stable/… canonical✓ - gtk-common-themes 0.1-81-g442e511 1535 latest/stable/… canonical✓ - snapd 2.63 21759 latest/stable canonical✓ snapd thunderbird 128.1.0esr-1 507 latest/stable/… canonical✓ - $

If I start firefox from the shell command line, it runs fine. It runs the shell script in /usr/bin/firefox, which ultimately executes /snap/bin/firefox. Clearly that shell script is doing some configuration that I don't understand.

If I​ hit Alt-space I see the menu in the referenced screen grab (see attached).

If I select the first entry, to run firefox from the command line, it has the same effect as starting /usr/bin/firefox from a bash shell; it works fine. However, if I select the third entry, firefox does not play any video; I've mostly tested with YouTube videos that have actual video and audio.

I'm not sure what gets executed when I select the third option from the Alt-space menu. It appears from doing a "ps -ef" that it's the same /snap/firefox/... executable. But I'm wondering why is this entry in the Alt-space menu and how does it get initialized or 'configured' to run.

Additionally, if I do start firefox from the entry with the firefox browser icon, and it fails to play video, I must then uninstall firefox using snap and then reinstall in order to get video playback to work. That is, after a failed start, simply exiting firefox and restarting it from the shell command line will not work; firefox will not play video correctly at all.

I also noticed that on my PC desktop, "snap list" lists firefox as "firefox 129.0.2-1 4793 latest/stable mozilla✓ -"

But on my old Lenova laptop running the same kubuntu version, "snap list" lists firefox as "firefox 129.0.2-1 4757 latest/stable mozilla✓ -"

​I'm up to date on both systems via "sudo apt update"' and "sudo apt upgrade"

Even more frustrating, today, for the first time, despite starting firefox from the command line, video still didn't play. I had to uninstall firefox and reinstall it.

FF keeps replacing

http://mysite.domain.net:3344 with httpS://mysite.domain.net:3344

whatever I try to fix this behavior. Thing is that I own this server and there ever was't any SSL implemented. I mean this - never.

Other browsers (Chromium, Chrome, Opera) don't take such a forcing action, website opens like a charm. Why FF thinks it knows better which URL I really want to open?

I already googled _a lot_ in order to find solution, but no one worked.

Setup: Debian 11 Mate no proxy and no separate "internet security" stuff on laptop (other browsers with default settings confirm that) FF 102.11.0 ESR 64 no addons (all switched off)

already tried: browser.urlbar.autoFill false browser.cache.check_doc_frequency 1 network.stricttransportsecurity.preloadlist false browser.fixup.fallback-to-https false dom.security.https_first false

What else I could do to stop this madness? Thank you in advance for any help

I see where other people have posed this question but the procedure offered is not available to me.

I am using Firefox (Flatpak) version 121.0 on an Ubuntu 22.04 laptop.

On installing a new extension I should either see the extension's icon on my toolbar or else have a clear means of adding it. I have neither.

Clicking on the jigsaw icon in the toolbar, I get migrated to the about:addons page. On clicking the Extensions tab, I get the screen listing all installed extensions. Each extension has a ... icon beside it. But when I click on this, there is no "Pin To Toolbar" option.

What is wrong here ?

Hello, trying to verify the integrity of firefox-118.0.1.tar.bz2 I realized the GPG key has changed.

The following blog post details the change and shows the new key: https://blog.mozilla.org/security/2023/05/11/updated-gpg-key-for-signing-firefox-releases/

But when I download the key using the link provided (which points to keys.openpgp.org) the key I get is different from the key posted on the Mozilla blog page.

What is even more strange, is that the key from keys.openpgp.org declares in the comment that 14F2 6682 D091 6CDD 81E3 7B6D 61B7 B526 D98F 0353 is the fingerprint of the key (the same that is posted on the Mozilla blog) but it can't be because the key different.

So my questions: 1) Why Mozilla is posting a link to a key that is different? 2) Why keys.openpgp.org shows the correct fingerprint with a different key?

And, in the end, which key should I trust and why.

Thanks.

Hi,

I seem to having multiple problems with Firefox over the last few weeks...

This problem is - I can't unblock popups. I have got popup blocking enabled, with a couple of Exceptions - it's been working fine until I wanted to use it today. I have tried turning off popup blocking, re-entering the exceptions - nothing is helping!!!

Does anyone know what to do?

Thanking you Pedro

Prior to Firefox 116, I could have the normal scrollbar up and down buttons showing by making:

widget.non-native-theme.gtk.scrollbar.allow-buttons True

But now it seems to have no effect. This is under Linux/Mint/Cinnamon. Also, now long-pressing is doing smooth scrolling (I never want smooth scrolling anywhere) and can't find a way to stop that.

I have these set from before:

widget.gtk.overlay-scrollbars.enabled false widget.non-native-theme.gtk.scrollbar.round-thumb false widget.non-native-theme.gtk.scrollbar.thumb-size .85 widget.non-native-theme.scrollbar.size 14 widget.non-native-theme.scrollbar.size.override 14 general.smoothScroll false general.smoothScroll.other false general.smoothScroll.lines false general.smoothScroll.pages false general.smoothScroll.pixels false general.smoothScroll.mouseWheel false mousewheel.system_scroll_override.enabled false toolkit.scrollbox.smoothScroll false ui.scrollToClick 0

Any suggestions appreciated.

Seems like it is always a fight retaining usable scrollbars in Firefox that do not hide, do not change size on mouse-over, do not "warp" on left click, do warp on center click, have a thumb that shows page size, have a background that is not white, and are not microscopic in size! Just call me "traditional"  :)

Thanks

Hello,

I have more than 30 extensions, but I cannot add an extension shortcut into my toolbar and no extension appears in the “Customize Firefox” view. I tried “Restore defaults” without any effects...

There is a way to fix this issue or run Firefox in verbose mode to more information why my extensions don't appear here? (Other than restart from a new fresh profile if it's possible…). I confirm that all the extensions are functional and activated. Thanks,

Emeric

Firefox update required me to restart Firefox. I was unable to save a bunch of work I had done in a particular tab because Firefox seems to have refused to connect to the site I was working at until I update. THAT SUCKS!

Dear,

I need to recover my Mozilla (Firefox) account on my computer after this latter crashed. Unfortunately, apparently I don't have the good password. Probably I used an automatically generated password which I don't remember.

I still have my account connected on my Android smartphone, but I can't access the account details (no way to recover my password or change through this device?!), and I can't export my bookmarks. Also, apparently all my identifiers and passwords were not synced on my smartphone :-( Hence somewhere all my precious information are available, but stupidly enough I can't access it anymore and resetting the password warns me that I might (is it even a certainty or a possibility?) lose everything. It seems that I cannot even produce a revovery key (to reset pwd without losing data as mentioned in the Help pages) as I can't connect on a desktop browser anymore (but well on my Android version). I am lost and just stupidly blocked - this is SO frustrating, I initially thought it would be a good idea to put everything in Mozilla - well...

Is there ANY way to actually recover my account without losing data on my desktop Firefox, given I still have access to the email account associated to the Mozilla account (and to the original emails from the creation of my accounts) and I still have access to my Firefox account on the Android app but this one doesn't seem to allow to do anything interesting in my case??

Thanks a lot!

I got sick of Winblows and it's been awhile since I ran Linux so I am now on my third flavour in about 2 months - Manjaro, Debian Bullseye [Mate] and my current daily driver Kubuntu. I think Kubuntu is a keeper (until I re-familiarise myself with the Linux OS - maybe a year or two) but still testing.

My issue is that on everyone of the 3 flavours I have tried Firefox is the main browser by default and I use it as my default on Winblows also for about 25 years or so in it's various incarnations (IE Netscape)

My issue with this is Firefox on Winblows rarely if ever crashes ()I can't recall the last time Firefox on Winblows crashed it was that long ago) but on Linux this is a completely different story.

ON Manjaro it crash 4-10 times randomly per hour. ON Mate it as fairly stable but still crashed 4-10 times per evening session (usually 5PM to about 11 or 12 PM) On Kubuntu it as unstable at first but then I got some updates and thing became stable for about a week or so - and by stable I mean 1-2 crashes every few days - so not stable but stabler. I just installed the nvidia driver version 515.x.x for my Nvidia 1070 and immediately after the reboot Firefox started crashing on every single tab I opened. I would re-open it and 10-30 seconds later it crashes again.

After 5 minutes or os of crashing a firefox update magically appeared to upgrade to version 106.x.x. and so I took it thinking it might make things better. It did not make things better. It made things MUCH worse, now it crashes everytime I try to open it.

I ALWAYS have at least 2 browsers installed just because of BS like this. I opened up Vivaldi 5.5.2805.42 and it opened, did not crash and is still open. I am tying this post for help using it.

Firefox extensions installed : ublock, newtab URL redirector,WebRTC(permanently disables WEbRTC and = keeps it disabled through updates, download helper and that's it.

Vivaldi extensions installed: uBlock, download helper - vivaldi doesn't need a new tab URL redirector because it has a configuration for newtab URL - as all browsers should (hear me Mozilla!), doesn't need WebRTC as it also has a configuration for this to turn it on or off and upgrading Vivaldi retains all config settings always and everytime I use it and update it - which admittedly is not nearly as much as Firefox and I am going to keep an eye on that one configuration for sure.

I want to use firefox, I really do, I love it - even through all the changes over the past few years I still love it -even though I HATE some of the changes. That being said it needs to be stable on my OS of choice.

I donate to the Mozilla foundation because I like their efforts on net neutrality and privacy. I also donate to varios net neutrality and privacy orgs such as the EFF and openmedia to mention 2 more. I am going to try to downgrade my firefox version because in my short Linux experience that usually does the trick. However the minute I decide Firefox is not stable enough on linux and swap out to Vivaldi instead my donation money goes from Mozilla foundation to the Vivaldi developers. NOW thats not a threat, I am sure the Mozilla foundation wont miss my $60.00 yearly but, it can;t just be me thats disappointed with Firefox on Linux and in fact google searches shwo me it is not.

Are politics more important than the MAIN PRODUCT of the Mozilla foundation? If not you gotta show Firefox on Linux some more loving because there are millions of firefox users round the world who are disappointed by my basic non-scientific search results and reasoning - which cannot be far off.

I mean - it won't even start and it constantly crashes when it does start.

Hi, Various Sites (sometimes firefox as a whole) keep crashing regularly. I am running Arch Linux (6.4.12, default kernel) with Hyprland WM on an old i7-7700K with a Nvidia GTX980TI. Apart from Firefox the system runs stable. When doing research, or just browsing text based sites, firefox is also very stable, but on some sites like twitch, youtube, or idle games like "Antimatter Dimensions" (ivark.github.io) the browser (or page) crashes regularly. It also happens in Troubleshoot mode, also after a clean re-install (including deleting /.mozilla in /home) and since various versions over the last couple of month. The latest crash report ID is bp-67ed2673-4ed2-452b-bc63-dc1060230831. I know I'm running a niche system, but I really like my setup and apart from those crashes it's amazing, so I hope you can help and point me in the right direction as to what could cause the crashes. Thanks for your time. KR, rehajel

Reposting from https://discourse.mozilla.org/t/firefox-upgrade-from-115-116-results-in-broken-screen-capture/121964

Howdy folks!

I am on Arch Linux and recently upgraded Firefox from 115 to 116 and this broke WebRTC screen capture. Whenever I try to share my screen in Microsoft teams and Google Meet, the participants only see a black screen with a cursor. I am able to reproduce the issue on this test page. I had to downgrade to 115 in order to “fix” this critical feature. Before that it was broken in 114 and I had to use Chromium for presentations. I no longer want to touch Chrome with a 100 ft pole since they are trying to introduce Web Environment Integrity.

The only bug I have been able to find is from three years ago:

https://bugzilla.mozilla.org/show_bug.cgi?id=1640771

I don’t want to add a “me too” comment, but was wondering how to show/give my support to get this issue fixed? It is crippling to my work workflow, and I don’t want to be on 115 forever. I am an engineer so I can provide advanced support to a Firefox dev, just not development as firefox is gargantuan beast of a code base.

Any guidance or pointers would be appreciated, Thanks!

Hello, I have seen a clear difference on the text that appears on the website (e.g. BBC Urdu) and same text in search results. I have tried different search engines (Google, Bing) and different browsers (Edge, Vivaldi) but same issue. Attached are the SS of the issue.

I am not sure if this has to do something with my DeepinOS. But would be thankful if can some guidance what to do? Thanks!

Using MX-21.3_ahs_x64 Wildflower. Since upgrading Firefox to version 116.0.3 all links within www.onlinetvrecorder.com do not work anymore. No messages, no hints what happened, just not working. Vivaldi has the same problem, Chrome works. I have asked in mozillazine, but did not get an answer.

After updating to version 121, the cursor theme, while having it on the window, changes from the default one (Breeze) to Adwaita while also getting like 2x bigger. How do I change it back to default theme and size?

Hi,

I have Firefox 102 ESR in Debian 11 (LXC in Chrome OS). It is the en_US version with Czech spell checking dictionary installed as an add-on. I can switch the spell checker from English to Czech in ordinary text areas by accessing the context menu via a right mouse click.

However, I'm using a proprietary e-commerce system (Shoptet) with a WYSIWIG editor that has its own context menu, overriding the default one in the browser. I can't switch the language for that reason. Is there a way to switch the spell checker language for a particular text area without access to the context menu? Thank you very much.
