Hello, please could you check, what might be causing crashes at start (even in safe mode). I have sent several reports:

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?

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've got FF set for https-only. But sometimes it will tell me no https is available but when I go to the site anyway it is https.

Is this a bug or is this something in my settings?

Using Mozilla Firefox 108.0 for Ubuntu canonical 1.0 on Ubuntu 20.04.

Thanks.

Hi,

first of all thank you all in the community for your amazing work on Firefox!

I have cloned my $HOME (including ./.mozilla/firefox/) to another Linux device.

Now I realize that changing the Firefox Sync device name on the new device would also change it for the other device when checking "Connected Services" https://accounts.firefox.com/settings. I also can only see the new device name when using "Send to device" from any device.

I guess I have to unlink my new device and somehow assign it a new device ID for Firefox Sync to recognize the new device. How can I do that?

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.

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?

For information: OS: EndeavourOS with Linux 5.15.94 DE: Xfce 4.18 with Xfwm 4.18 Version: Latest, Firefox 110, installed from Arch Linux repository

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.

Hello, I'm using Firefox 100.0.2 (OS: Ubuntu 20.04). It is not possible to manage if/when firefox updates are installed. In the options-section, there are some information about the current version number, however no chance to configure anything update-related. Updates just happens automatically and interrupt current sessions, leading to spontaneous (and surprising) dysfunction of the opened browser. That's very annoying in case of video conferencing, for example, because it is not possible to open any new tab or windows, always the note there "you have to restart firefox now" - in practice, just like a crashing error. And, the suggested restart does not re-open the current opened tabs/URLs!

Furthermore, within some updates, my language settings get lost, so it turns to English language automatically and I always must add my language packet manually again and again. Thats really annoying and maybe completely disruptive for people that are not able to read in English!

Is there any chance to come over this? Otherwise I guess I must leave using firefox as browser, however this would be not the aim I actually follow. Thx!

When I restart my computer, I am logged out of all websites although I did not select settings such as "Delete cookies and site data when Firefox is closed". This only happens with reboots and not on Suspend.

I saw two similar posts but the options look like they changed name since then: https://support.mozilla.org/en-US/questions/1319622 https://support.mozilla.org/en-US/questions/1289909

I tried to apply the solutions linked there, to no avail.

This behaviour only happens on my Garuda Linux and not on Pop-os. Thus I am not sure here is the right place to ask this question.

Another strange bug which may be related is the following: if I zoom in a page (say set it at 120 percents) then go to another tab and then come back to the page I zoomed in, the zoom is reset to 100 percents.

Any help would be greatly appreciated!

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.

I have deleted my bookmarks with the Bookmark manager, but where are they now? I cannot find them in /trash and all of the *bookmark* files on my laptop are miniscule (like 127 bytes.) The json files are no better, when I imported previous bookmark files they were empty.

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 haven't used my microphone in Firefox in years. I tried today, logged into Google Voice, which tells me it can't access the microphone. I set permissions in Firefox's settings. I turned up all the mic settings in alsamixer. I tried https://mdn.github.io/web-dictaphone/ , recommended in another thread here, and it doesn't record either. I can use the microphone outside X, with sox's rec. I also can't record a new greeting in Google Voice.

Firefox 100.0.2 , Linux, Slackware 64-bit, all packages updated this morning.

Maximizing and minimizing are still normal, but Firefox windows could not be dragged now.

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?

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.

When entering full screen mode it's only inside selected window. Also affects youtube player. Pictures when in full screen mode (using F11 key): https://imgur.com/a/gp3yqCC

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
