Firefox Community Forum

I'm on FF 154.0. The power went out here and when it came back and I booted the desktop computer something had changed in FF.

I used to see the active tab as green in the tab bar and yellow for the rest, but now they're all gray until I mouse over the bar and only then does it turn green/yellow.

I struggled with this for many hours trying many //active tab color// solutions I found in searches but nothing got it back to my old behavior.

So as a last resort I tried adding the Firefox Color extension, but when I click Add to Firefox it just turns into a throbber that never changes so it doesn't install. I'm stuck!

Frustrated!!

this exact question has been asked last year, none of the suggestions work: I am running Firefox 154.01 on Winux I have lost sound on Firefox. I have opened the same sites in Chromium and the sound is working fine. It's only in Firefox. I have tried several sites including , YouTube, and radio programs, no sound from Firefox. All of a sudden the sound disappeared. The speakers is turned on the volume is up, just not a sound from Firefox. What to do? Right now I had to switch over to Chromium

I run Firefox on a retro Linux system that is currently running a personal "Frankenbuntu". Basically, Kubuntu 14.04 LTS with lots of components updated either "in-tree" or via a pkgsrc-like collection of "ports" installed under /opt/local that includes GTk3, Mesa, VAAPI plugins etc. I use that tree with a combination of built-in rpath settings (for apps installed under /opt/local) and wrapper scripts setting LD_LIBRARY_PATH, so as to maintain the possibility to run system apps independently, in particular while booting. (Sounds complicated, but it's also a rewarding fun project for me, allowing me to keep using an old and familiar DE with modern features on 2017 hardware,)

I have never yet dared to update my glibc from the stock 2.19, so with every Firefox update I fear to run into problems with that. I do have a 2.27 build but that is installed in another parallel prefix (/opt/glibc/2) because one cannot simply use LD_LIBRARY_PATH to use a newer glibc (I think because the ELF interpreter, ld-linux.so, has to match).

I already use patchelf with success to change the ELF interpreter to the 2.27 one, for instance with Ferdium, a Node/Electron application. This works and as far as I can tell, it will load all Mesa and DRI components from my /opt/local tree so hw-accelerated video works as it should.

But when I try this with Firefox, I get what appears to be a sandboxing issue when attempts are made to load Mesa DRI libraries: ``` libva info: VA-API version 1.24.0 libva info: Trying to open /opt/local/lib/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_23 [GFX1-]: VideoBridgeParent receives IPC close with reason=AbnormalShutdown MESA-LOADER: failed to open iris: libsensors.so.4: cannot open shared object file: Permission denied (search paths /opt/local/lib/dri, suffix _dri) failed to load driver: iris MESA-LOADER: failed to open kms_swrast: libsensors.so.4: cannot open shared object file: Permission denied (search paths /opt/local/lib/dri, suffix _dri) failed to load driver: kms_swrast MESA-LOADER: failed to open swrast: libsensors.so.4: cannot open shared object file: Permission denied (search paths /opt/local/lib/dri, suffix _dri) failed to load swrast driver libva info: VA-API version 1.24.0 libva info: Trying to open /opt/local/lib/dri/iHD_drv_video.so libva info: Found init function __vaDriverInit_1_23 [GFX1-]: VideoBridgeParent receives IPC close with reason=AbnormalShutdown ``` Copying libsensors into /opt/local/lib turns the above error into the same one about the next library available in the system (/lib/x86_64-linux-gnu/libtinfo.so.5). The DRI module I actually need (iHD) does load but I still get the GFX abnormal shutdown error. I've tried the interpreter change in other applications using libva and don't see the issue.

I do see this in the syslog: ``` Aug 31 15:18:47 Bmbl kernel: [2043645.959690] MediaSu~isor #1[17692]: segfault at 290 ip 00007f2b0815b284 sp 00007f2ad913e990 e rror 4 in ld-2.29.so[7f2b0814f000+21000] Aug 31 15:18:47 Bmbl kernel: [2043645.959702] Code: 04 49 83 fc 06 44 0f 44 c8 81 e6 ff 7f 00 00 45 89 8f 08 04 00 00 48 8d 04 76 4d 89 b7 00 04 00 00 4c 8d 04 c7 4d 85 c0 74 0f <41> 8b 48 08 b8 00 00 00 00 85 c9 4c 0f 44 c0 41 8b 3e 6a 00 48 8d Aug 31 15:18:47 Bmbl kernel: [2043646.080407] MediaSu~isor #1[17732]: segfault at 290 ip 00007f2b0815b284 sp 00007f2ad913e990 e rror 4 in ld-2.29.so[7f2b0814f000+21000] ```

Any idea why this is, and what can be done to prevent this, beyond actually updating my system glibc? I'd have no problems disabling sandboxing.

I've been using the split view feature and really like it... however I constantly find myself doing the following:

Having a split view open with related pages, for example a list view in the left pane, and I want to open one of the items in the list view in the opposite pane, currently I have to:

1. Copy the url in the left pane 2. Switch to the right pane 3. Target the address bar 4. Paste the url 5. Load the new url

Ideally an additional 'open link in x' option could be added specifically when a user is in the split view, that will open the link directly in the opposite pane of the current split, so left > right or right > left.

My question is, is there is a way to do this already; I cannot find any reference to this in the docs.

"Open Link in Opposite Split View" would be perfect.

Environment

   • Firefox 153.0.1 (64-bit)
   • Ubuntu 24.04.4 LTS
   • Wayland session
   • Input method: IBus
   • Keyboard layouts:
       ◦ US
       ◦ Bulgarian (bg+bekl)
   • Graphics:
       ◦ AMD Radeon Graphics (renoir)
       ◦ WebRender (Software)

Summary When typing a multi-word search query in Bulgarian into the center search field on the Firefox New Tab page (about:newtab), the first word disappears immediately after pressing the Space key. The issue occurs only in the in-page search field. Typing exactly the same text in the Firefox address bar works correctly. Steps to reproduce

   1. Open a new tab (about:newtab).
   2. Click inside the center search field.
   3. Switch to the Bulgarian keyboard layout.
   4. Type the first word, for example:   български
   5. Press the Space key.

Actual result The first word disappears completely. The search field becomes empty and the caret remains after one blank space. Typing continues normally from the second word onward. Interestingly, pressing Ctrl+Z immediately restores the missing first word, indicating that Firefox performs an undoable edit operation rather than simply ignoring the input. Expected result The first word should remain in the search field after pressing Space. Additional observations

   • The problem does not occur when typing in the Firefox address bar.
   • The problem does not occur on google.com or in other web page input fields.
   • The problem is reproducible in:
       ◦ Troubleshoot Mode
       ◦ a brand new Firefox profile
   • No third-party extensions are installed (only the built-in OpenH264 codec is present).
   • Setting

browser.newtabpage.activity-stream.showSearch = false removes the in-page search field, therefore the issue disappears because the affected widget is no longer present.

   • Disabling

browser.search.suggest.enabled does not change the behaviour.

   • If the address bar already contains text before clicking into the New Tab search field, the issue may no longer reproduce. This suggests that the bug could be related to focus handling or interaction between the New Tab search widget and the address bar.

Reproducibility Always reproducible on this system. Notes The issue appears to be specific to the Firefox New Tab search widget (about:newtab) rather than to the operating system, keyboard layout, input method, or user profile. ____________________________________________________________ The text above was created following extensive discussion and numerous tests, in collaboration with ChatGPT.

all tabs failing to play; is this a profile grep e unlock issues; GROK 5 linux ubuntu link action: terminal commands: ps aux | grep -i firefox ; kill -9 those PIDS; is the number one cause of firefox silently failing to relaunch after a hard kill

Up until recently (apologies, I do not know which version) when editing userContent.css on Debian 12 in the ' Developer Tools ' I could just use CTRL+S to save my changes and all was well.

Now it appears to have forgotten where it loaded in the first place, because (when using the shortcut or the 'save' link under the name on the left) it just opens the user's home folder at its root level or ' ~/ ' ...

Is this a bug that I should raise at bugzilla? Or has another bug fix messed this functionality up somewhat?

This is the ' mozilla-deb ' / ' Mozilla Firefox Debian Package ' currently at version 154.0 which is usually updated weekly.

Well, I am in a real mess. Three days ago I lost the ability to access my favourite website. I CAN access the website in the Brave browser. The website owner has told me that it is not a problem with my account with them so it must be a Firefox issue. Before this happened I had been trying to move and delete files on my laptop and have got very confused about EVERYTHING. In that I had deleted my Firefox recovery folder(s). I have managed to move them back into my Home folder before they expire. Now I am being asked to enter my "password" to initiate the restore. But the several Firefox passwords in my laptop are not being accepted. How can I get a new password? If that is not possible do I have to delete my Firefox account? What is my best way to recover from this mess? Any advice is greatly appreciated.

Started OBS Vitrual Camera option. in Firefox the camera is no listed.

https://webrtc.github.io/samples/src/content/getusermedia/gum/

only shows phyiscal cams.

How can virtual cameras listed in Firefox?

``` $ v4l2-ctl --list-devices --all OBS Virtual Camera (platform:v4l2loopback-000):

       /dev/video0

SandbergCapture: SandbergCaptur (usb-0000:07:00.0-1):

       /dev/video1
       /dev/video2
       /dev/media0

```

but OBS Virtual Camera is not listed

I run normal firefox on linux. Fully up-to-date. Every time I quit the app, it reverts to a version of my profile from a month ago, and loads all the tabs I had open then, and then receives all the tabs that I sent to the device in the interim (~1 month). As I speak, it just caught the 60 or 70 tabs in this window.

I tried changing the name of my profile folder to randomstring.defaultOLD and changed one of the backups to randomstring.default. This didn't change the behavior. I'm still stuck in the loop. I saved my tabs with onetab, because firefox isn't remembering my session anymore. I thought it was something to do with updates, like it only loses its mind upon updates, but that's not true. It thinks it's updating firefox EVERY TIME, because the one time it's loading to 1 month ago it was updating, but I'm 100% sure there are no updates to firefox in my linux. It's just hallucinating.

The articles on restoring from backup are outdated. They say to use an html file. There is no html file. It's just folders for profiles, not html files. HELP!

I've been relying on backup/recovery from backup because firefox now deletes my profile/session every time it does a meaningful update (several times a month).

Now, one stupid/broken thing is that I have to re-enable backup every time I restore my profile/session (this setting, backup ON, should be included in the profile/session!).

The second broken thing is that now I can't re-enable backup today, after yesterday's update.

I can fakely turn backup ON, but when I click "backup now", I always get "Hmm, there was a problem backing up. Learn more"

Learn more has no useful information. Waiting a few minutes, like it suggests, does nothing. Now, I'm going to get my profile deleted the next time firefox updates, and I won't even be able to restore from backup.

Finally, whoever's in charge of this feature needs to learn English. Log in is a verb, login is a noun and an adjective. Similarly, back up is a verb, backup is a noun and and adjective. You can't "backup" your profile. You BACK UP your profile. A backup is a noun. You can't do nouns. You do verbs. I back up my profile. I back up (verb) the backup (noun) in a backup (adjective) file.
