Firefox Community Forum

I updated Firefox and an old version remains on the "show applications" screen. I suspected it might be another profile, so I went to about:profiles and removed it, but it's still there. As I am relatively new to Linux (Ubuntu specifically), I would appreciate some help with this issue.

Firefox will no longer display the main window. I get an icon in my taskbar but the window is nowhere to be found. I've tried the tricks of maximizing it and moving it but neither works. I have found that if I locate the xulstore.json file it will work but only for a short time. Next time I start Firefox I get an icon but no window. Very frustrating!

The sulstore.json file contains nothing that suspicious:

``` {"chrome://browser/content/browser.xhtml":{"main-window":{"screenX":"2129","screenY":"777","width":"1280","height":"1040","sizemode":"maximized"},"sidebar-box":{"sidebarcommand":"","style":""},"sidebar-title":{"value":""}}} ```

If I start Firefox and right-click the icon, select maximize it's as if it's maximized covering all my windows but yet invisible. I can see my other windows but I cannot interact with them.

Deleting the xulstore.json file often fixes this but it breaks again shortly. What's the deal???

Hi all, I'm having a lot of problems with Firefox crashing pretty often. Sometimes once or twice a day.

I most often see crashes in the middle of a Webex video conference for work. But Firefox sometimes goes down in other situations that I see no pattern in.

This is Ubuntu 20.04, Firefox 102.0. Unfortunately, it's a complex environment to debug.

First, when firefox goes down, it rarely leaves a crash report behind. So I'm not getting any direct evidence as to what is happening. Second, I run with uBlock active and it is very difficult to function in the browser without long enough for the crash to happen. Third, I typically have several hundred tabs open. I have a lot of memory (64G) in my machine, and the machine doesn't act like it's swapping, so I don't think I'm running out of memory.

Any help getting to the bottom of what's going on is welcome.

Whenever a website prompts for me to upload or download a file and I except Firefox crashes, quitting in its entirety. This still occurs in "Troubleshoot" mode so I assume it is not any of my extensions. Here is a crash report from when this occurred if it helps. Another odd observation I made is that I am able to upload a file if I use a "drag-and-drop" feature on a website.

Hello, I would like to report an issue with Firefox 113.0 cannonical-002 1.0 on Ubuntu 22.04 lts. When opening 5-8 tabs, the browser consumes a lot of memory. When the system's RAM usage, along with the browser, reaches 80% of the computer's memory capacity (12Gb is the full size of the machine RAM), the browser crashes without generating any crash reports and does not restart itself. Interestingly, using the same browser on the same hardware, but on another OS, Windows 10 with the latest stable version of the browser, with the same themes and add-ons, the issue is not observed, and memory usage is much lower.

Could you please suggest a solution to this issue and help prevent these crashes from happening?

Thank you for your time and assistance.

I am going through the https://support.mozilla.org/en-US/kb/containers#w_manage-your-containers page and I dont have the option to add new containers when I click on the icon. I am only shown the choice to open the current page into one of the default containers. If I open a new empty tab, this icon doesnt show up in the url bar.

I have gone through the manage extensions options as well and I cant find a similar option. Can anybody point out what I am missing?

Operating System : Ubuntu Lunar Lobster (23.04) x64 Firefox version : 116.0.3 (64-bit) installed via snap

This isn't a constant issue for me, but occasionally the browser will suddenly break such that when I switch tabs, nothing actually updates until I do something like restore/maximise the window. I can still interact with the page itself, but whether using the mouse or keyboard shortcuts, changing, opening, or closing tabs, or even typing in the navigation bar, won't do anything until I resize the window again. I haven't been able to figure out any pattern to when this state triggers, but after it does, it doesn't clear up without closing and reopening the browser. I have recorded a video showing this behavior but I am unable to upload it here, and still images would not properly convey the issue.

I'm a Chinese user, and all my firefox account in other devices( windows10, IOS) was login in page https://accounts.firefox.com.cn", but using firefox in ubuntu, it was redirect to https://accounts.firefox.com. Even i login with the same e-mail, the data can not be syn, and i have known the reason was there are two different server for Chinese.

But i need a way to syn data in Ubuntu, please tell me how to deal with that. 3Q !

I use Firefox to download, copy, and store WikiSpecies pictures.

Currently, my .../Documents/WikiSpecies/Animalia_Plantae_8 directory holds what it says are 90,876 items, totalling 11.5 GB. I have plenty of unused space in that directory (over 91 GB), so space is not an issue.

Lately, when I try to install a new picture, I keep getting a warning that the picture is already stored. This MAY be because I am running out of new pictures, but I can't tell.

Is there any capacity limit to a WikiSpecies directory?

These websites won't play audio or video in Firefox 110.0.1, they work in Chrome 110.0.5481.177

https://www.vrt.be/vrtnu/livestream/audio/stubru/ When I click the Play button I get an error "Oops, something went wrong, error code 200" which seems to be a general error code. In Chrome the music starts playing instantly.

https://f1tv.formula1.com/ I have a subscription but video won't play. I can press the Play button, sometimes I see a preloader but the screen stays black, no audio or video. In Chrome the content just starts playing, be it live or recorded content.

Steps I took to get audio/video working inb Firefox, but to no avail:

run above websites in private tabs download Firefox again and run it from its folder in Downloads start Firefox in Troubelshoot mode start Firefox in Troubleshoot mode and Refresh Firefox disabled / enabled Plugin Widevine Content Decryption Module provided by Google Inc disabled / enabled Play DRM-controlled content in Settings disabled / enabled Enhanced Tracking protection disablde / enabled allow media autoplay

In other discussions it was opted to remove the PulseAudio config by running the below command and rebooting rm ~/.config/pulse/*

Any help to get this working again would be greatly appreciated!

[edited] @yahoo.com . Trying to synchronize with my computer and i can not get it to work . Have scanned the code on computer ( Ubuntu 22.04 desktop three times & it nust shutsdown. Can you help me synch my browser ?

Hi, I've been struggling with this for months and can't find an easy solution or a good explanation. I'm running Ubuntu 22.04 pretty basic, I don't have many custom repositories enabled or anything, just a few additional packages like slack, Teams or Chrome. Ubuntu switched Firefox to snaps as well, and I can't get internet access with it. The error message is:

--- May 12 12:16:20 nuc kernel: [12948.381392] audit: type=1400 audit(1683886580.562:131): apparmor="DENIED" operation="open" profile="snap.firefox.firefox" name="/etc/fstab" pid=7731 comm="firefox" requested_mask="r" denied_mask="r" fsuid=1000 ouid=0 May 12 12:15:43 nuc rtkit-daemon[1030]: message repeated 3 times: [ Supervising 10 threads of 4 processes of 1 users.] May 12 12:16:20 nuc dbus-daemon[790]: [system] Activating via systemd: service name='org.freedesktop.hostname1' unit='dbus-org.freedesktop.hostname1.service' requested by ':1.175' (uid=1000 pid=7731 comm="/snap/firefox/2645/usr/lib/firefox/firefox " label="snap.firefox.firefox (enforce)") ---

Simply stopping (and aa-teardown) doesn't work at all, Firefox doesn't even start without apparmor running. I'm not an expert with apparmor, but I wanted to set in complain mode instead enforce, but I'm struggling with that, too. I didn't touch the /etc/hosts file, the error message is a little different on another Ubuntu 22.04 computer I use, there it complains about permission denied for the resolve.conf. So I'm asking the community, how do you deal with this? Searching the web gives me all kinds of ideas, but none of them work. Could anyone help me out here?

Thanks!

Hi,

So, it looks like snapd went ahead and updated my Firefox.... Grrrrr

Now I'm unable to access my profile information. (passwords, tabs, extensions, history, etc)

When I try, I get a pop-up telling me that using an older version if Firefox can lead to profile data corruption. However, I'm trying to use FF version 109.0.1 (64-bit), which should be very new.

How can I get my profile data back?

Thanks in advance,

Mike Diehl.

Hello Volunteers,

Ubuntu crashes while moving around a Firefox tab with a mouse, IF the mouse cursor goes thru the top bar of the laptop screen. I am using Firefox V 113.0.2, Build ID: 20230522193126 on Ubuntu 23.04. This could be an Ubuntu problem or a Firefox problem.

Thanks Dilip Deodhar

I was able to use the media buttons on Ubuntu 22.04, until I re-installed Ubuntu on a new drive.

After the re-install, when playing media on Firefox (like on youtube), the pause button on my keyboard does not work, and GNOME notifications does not show the video that is playing (it used to).

Other apps work fine (such as vlc media player), and I cannot figure out why it suddenly stopped working.

Thanks!

I want to attach a file and I click on a button (everything works perfectly on Chrome). When I click, in the console I get this error:

(firefox:3264): Gtk-WARNING **: 13:52:46.781: Can't open portal file chooser: GDBus.Error:org.freedesktop.DBus.Error.UnknownMethod: L’interface « org.freedesktop.portal.FileChooser » n’existe pas pour l’objet à l’emplacement /org/freedesktop/portal/desktop

Of course, nothing happens when I click. I have Ubuntu 22.04 and apparently Firefox in installed with snap, and I have this problem since snap is used to install Firefox.

If it's useful:

This message is the last I'm writing before I definitely move to Chrome. I hope I'll get the help I couldn't find on other places (I saw a lot of answers telling to deactivate snap, adding a ppa or some solutions like these).

I am using Ubuntu Firefox 110.0 (64-bit) on Ubuntu 22.04 x86_64. I am unable to play contents on Disney+, Amazon Prime Video Netflix and such. I was streaming fine until a few months ago. I have checked my settings and they are all properly set. At the time I am writing this report, the Widevine Content Decryption Module is at Version 4.10.2557.0, updated to its latest release. Obviously DRM content is enabled in settings. Changing the useragent did not solve the problem. I have seen this problem reported before for MacOs users but I could not find anything for linux users. Am I the only one having this problem? I hope someone can help. Thanks
