I can't access the keyboard hotkeys config page as instructed in https://support.mozilla.org/en-US/kb/customize-keyboard-shortcuts-firefox. Typing about:keyboard into the address bar gives an Invalid URL error, as seen in the attached screenshot. I am able to access other about: pages.

How do I keep my online banking private when using Firefox as my browser? When using Google Chrome as my browser, I use incognito, but I'm changing to Firefox and need to know that my online banking is safe.

Hi,

I'm using Firefox 155.0.1 64bits, in Linux Mint Debian Edition 7, x11, XFCE4. I have a Belgian keyboard. I have noticed that the dead keys aren't working any more when typing text / messages from within Firefox. I don't have this problem in other browsers or applications.

I used xev (x11 utility) to check if the dead keys were working and tested a different keyboard, all work. I tried to start Firefox in safe mode or by starting Firefox from a terminal with the following commands: - env GTK_IM_MODULE=xim firefox - env GTK_IM_MODULE=ibus firefox

But nothing worked. The dead keys aren't working. The issue must come from Firefox for it is not an hardware issue (tried different keyboards) nor software (dead keys work in other applications).

Any idea to fix this ?

Where is a link, icon, or ANY WAY to add a shortcut site to my Ubuntu FF **DESKTOP** homescreen?

I already have 4 rows (since 2013 over many Linux laptops. Ubuntu, Mint, popOS, and now Ubuntu 26.04 LTS).

There is room in the fourth row for a few more. BUT I don't see any icon or link or right-click option to add another!

Phrasing the article search various ways gets me a lot of unrelated stuff.

EVERY help article, of which there are few, seems to have a BIG-ASSumption that everyone is using mobile Firefox.

NO! NO three dots. No right click brings up anything. NOTHING in settings. I've been through everything in the 3-bar menu, and there is NOTHING. (I already use it to sync, go to OTHER settings, go to help, etc.)

This is a day after an update, though I don't know how that affects it.

Usually if I forget how I did something, I just explore and find it. BUT --

My way of adding new shortcuts seems to be GONE.

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.

There must be some setting I accidentally engaged by hitting some kind of key combination but there are the contents of 2 separate tabs on the FF window. Maybe it's some new 'feature' they added but I right clicked on the tab and nothing looked like it applied to this. What is it and how can I make it stop? I just want each tab to have the contents for that site. If you know what's going on, maybe explain it simply and I'd also like to thank you.

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!

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

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.

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.

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
