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

Hi there,

I'm using my PC for local web development. I use Firefox as my regular browser and recently, in order to distinguish between personal time and development time, I've established a new profile just for development purposes.

The local website I can't reach is "site.local.dev". My OS is Ubuntu 20.04 and that URL points to a local IP on my network (resolved via /etc/hosts file on my PC).

Funny thing is that: - In dev-profile: site.local.dev does not work => "Unable to connect" and the URL bar shows https://site.local.dev even if I force it to http:// - In personal-profile: site.local.dev does work :P

I have tried with CLI tools like "wget", "hosts", "ping", "telnet" and so on and the site loads ok. Even I have used Dillo (damn simple web browser) and the site loads ok also.

Things I've tried so far: - Suggestions at https://support.mozilla.org/en-US/kb/firefox-cant-load-websites-other-browsers-can - Suggestions at https://support.mozilla.org/en-US/questions/1011327 (similar issue, not exactly the same).

It must be a silly thing but I'm out of options now. Perhaps anybody has faced to this situation in the past: any suggestion on this issue?.

Thanks in advance, Ibon.

I am experiencing problems when using Duolingo, which is highly interactive.

This same problem was highlighted in Version 95.0.2 from a Windows user. The waveforms on System Monitor/ Resources are the same.

I am using Fedora and have 16GB ram. Have just ordered another 16GB ram, but think this problem is so severe that no amount of ram will fix it.

Firefox unter ubuntu 22 hat keinen Zugriff auf die lokalen Dateien (z.B. /usr/share) Der 'open' auf '/usr' scheitert mit 'read'-Zugriffsrecht.

Ganz egal, was in '/etc/apparmor.d/usr.bin.firefox' respektive in '/etc/apparmor.d/local/usr.bin.firefox' spezifiziert wird, das Zugriffsrecht für '/usr' ist immer 'read'.

Wie kann man auf die Dateien unter '/usr/share' zugreifen?

Mit freundlichen Grüßen

Thomas

Firefox says I need a video codec to play a video (that is aparently somewhere on the page). It does NOT tell me what video, what video format, or what codec I need. How do I find out what codec I need?

Firefox version: 101.0 (64 bit) OS: Fedora 36

I was using Ctrl+K on some websites to do things like site-specific search, task bars, and so forth, but recently Firefox started capturing it for focusing on the search/address bar (https://support.mozilla.org/en-US/kb/keyboard-shortcuts-perform-firefox-tasks-quickly#w_search).

Is there a way to unbind `Ctrl+K` in Firefox?

I am not able to download any kind of file, from any kind of website to my disk. I am able to select open on the download dialog, and this will open the file and save it to the temp directory firefox uses for this function, but this does not save the files to disk/the download folder like I want to. I am unable to "Save image as..." as well, since this is considered a download. There is no record of these downloads even being attempted in the download history.

Hello,

I have activated Firefox Sync and "delete cookies on close" and I have noticed that the URLs I have set up exceptions for do not sync across my devices, thus having to re-enter them on every device.

Is this by design or can I do something about it?

Thanks for any help

I have a linux debian 11 o/s with up-to-date Firefox I don’t know which version at the moment it is whatever debian repo pushes down. I have 5 profiles on this particular computer with no previous issues. I decided to create another profile to be used for some test work and when I created it I then launched it and opened a few tabs to make sure it worked then closed. I planned on copying the profile files from another profile into this one so I went to the profile folder - /home/user/.mozilla/firefox/profile.names

Once there I saw my other profiles but could not locate this one so I went back to an open browser where I had the about:profiles page open and decided to delete that new profile and start over I figured maybe I accidentally saved it to a different directory. I hit remove it and it gave me the box asking if I wanted to remove files I chose yes I then go back to - /home/user/.mozilla/firefox but folder firefox was gone with all of my profiles all that was left in .mozilla was - /home/user/.mozilla/extensions and - /home/user/.mozilla/systemextensionsdev. Both of these folders - “extensions” as well as “systemextensionsdev” are empty. I go to the local directory for each profile and the data is still there for each of the profiles - /home/user/.cache/mozilla/firefox/profile.name.

The recycle bin is empty. A system-wide search for the profiles comes up with just the ones in the .cache folder. Back at the about:profiles page any attempt to open the preexisting profile results in a prompt asking me to create a new profile. I still have the one profile open and the addons are not working correctly. I did a bookmark export on this profile and doing so generated the “firefox” folder that had disappeared plus a profile folder using the same name of this open profile - /home/user/.mozilla/firefox'profile.name - it created a profile folder for this open profile using the correct name.

Any ideas on how this happened? Can the local profiles still in .cache be used to somehow restore the full profiles?

Problem: Scrolling in firefox is feeling weird: instead of smooth scrolling with 2 fingers (like on smartphone with 1 finger) firefox scrolls only by steps only when I move my fingers enough to trigger scrolling. In other applications I can scroll smoothly and fully control scrolling, I can scroll exactly N pixels if I want. In firefox I can only move by N pixels per M cm fingers movement on touch pad.

It's feeling as indirect input. I can feel same feeling on Windows with simple mouse. Firefox scrolls slower than Opera.

How to reproduce and find difference with other applications:

1. Download Firefox and another application with direct input (Opera or Telegram for example)
2. Scroll Firefox
3. Scroll another application

Hello

We have lost our developer access to manage an extension. Nobody knows which email address and account was used to manage the extension.

What is the procedure to get ownership of the extension ?

Thanks Frédéric Jahard

So, a preface. I rarely used this PC of mine, and thus the Firefox is rarely used as well. When i installed it, i turned on the option 'Open previous windows and tabs'.

Then, once I opened up some kind of offline documentations from Libre Office or Latex, which opened in Firefox. You know, the one where there is no tab appeared, and it just seems like a single pop-up window. I closed it without thinking.

Long enough, i forgot about that and opened up Firefox only to be met with that docs again. Okay, i closed it. But Firefox always started in this kind of pop-up window style ever since (attached). Changing the preference, even deleting the profile doesn't seem to do a thing.

Any recommendation to return Firefox to its original set?

I really often need to copy/paste from a terminal opened in my browser. Because the shortcut for copying in a terminal is always Ctrl+Shift+C, it's a mess to have instead Firefox opening Inspector from devtools.

How can I disable this shortcut ?

I've tried to update some about:config settings but it doesn't seem to be helpful and old working correctives add-ons are not supported anymore.

I have different login forms on different sub domains so I always get a huge lists of different logins. and also I get my password for the basic auth from the web-server on my login form.

I also consider this as a security risk when different sub domains belong to different parties and I accidentally put my password into the wrong form.

Can I config Firefox the way that I get only passwords in the list that match the exact url or at least the (sub)domain?

Another Question As a Web-developer can I do something that my client don't experience such a mess (like giving the login form a special id so passwords are restricted do this particular form.

I'm trying to install Firefox on a Chromebook. I've done this successfully before. Using the instructions in the Mozilla page https://support.mozilla.org/en-US/kb/run-firefox-chromeos?utm_source=www.mozilla.org-firefox-browsers-chromebook&utm_medium=referral&utm_campaign=seo#w_installing-the-firefox-desktop-browser-with-flatpak

But the command in the terminal window sudo bash -c "$(curl -fsS https://raw.githubusercontent.com/mozilla/sumo-kb/main/run-firefox-chromeos/install-flatpak.sh)"

Is giving me the error message curl: (22) The requested URL returned error: 404

Any advice would be appreciated! This is a fresh ChromeOS environment since I just did a factory reset so everything should be clean, and with latest OS version.

Thanks

I saw where this was a problem with Netflix, Amazon Video and other sites with Fire Fox and that one person even used professional version and still had the same problem.

What I cannot see is where he got the video codex that allow Netflix to work on Fire Fox version 88, let alone this newest version that Mozilla has created.

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.
