Firefox Support Forum

I recently switched over to Firefox and for some reason there's just no way to adjust the volume on Twitter. It's either muted or full blast and I'd like to know how to bring back the little slider. I've tried what people posted on Reddit and neither the extension or the Tampermonkey script did anything. I don't know what else I can do.

Hello! After updating from 108 to 122, there's no restore previous session button. The recently closed tabs option only returned half of the tabs. Will this bug be repaired and how can I get back the tabs?

Hi,

  I am running the latest Firefox v122 (firefox_122.0+build1-0ubuntu0.22.04.1~mt1_amd64.deb not snap)

and when using the --profile option to specify the startup profile it fails to start even on a NEW system that never ran Firefox if I give it a directory that resides on a mounted ext3 filesystem.

  All the permissions are OK and yet running strace I see an error and after a few second will get the

generic pop-up with the error message: (after a few seconds)

Firefox is already running, but is not responding. To use Firefox, you must first close the existing Firefox process, restart your device, or use a different profile.

 Running the SAME from /tmp works fine, but I need the profile to reside on a persistent storage area

so if the LIVE distro restarts then it can restore the previous session, bookmarks, options, etc...

============================================================

 The 2 directories were created identically and have the exact same permissions:

xubuntu@xubuntu:~$ mkdir /tmp/firefox3

xubuntu@xubuntu:~$ mkdir /media/xubuntu/sys_n01_home/mozilla/firefox3

xubuntu@xubuntu:~$ ls -ald /tmp/firefox3 drwxrwxr-x 17 xubuntu xubuntu 1080 Jan 21 22:05 /tmp/firefox3

xubuntu@xubuntu:~$ ls -ald /media/xubuntu/sys_n01_home/mozilla/firefox3 drwxrwxr-x 17 xubuntu xubuntu 4096 Jan 21 21:13 /media/xubuntu/sys_n01_home/mozilla/firefox3

============================================================

The only difference is that one is mounted on tmpfs and the other is on /dev/nvme0n1p2:

xubuntu@xubuntu:~$ df -k /tmp/firefox3 Filesystem 1K-blocks Used Available Use% Mounted on tmpfs 32560016 351528 32208488 2% /tmp

xubuntu@xubuntu:~$ df -k /media/xubuntu/sys_n01_home/mozilla/firefox3 Filesystem 1K-blocks Used Available Use% Mounted on /dev/nvme0n1p2 195751828 51056068 142695768 27% /media/xubuntu/sys_n01_home

============================================================

When starting firefox with the /tmp/firefox3 profile directory it works fine and starts up:

xubuntu@xubuntu:~$ firefox --profile /tmp/firefox3

newfstatat(AT_FDCWD, "/tmp/firefox3", {st_mode=S_IFDIR|0775, st_size=1040, ...}, 0) = 0 newfstatat(AT_FDCWD, "/tmp/firefox3/.parentlock", {st_mode=S_IFREG|0664, st_size=0, ...}, 0) = 0 openat(AT_FDCWD, "/tmp/firefox3/.parentlock", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 11 fcntl(11, F_GETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0, l_pid=-487933736}) = 0 fcntl(11, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = 0 uname({sysname="Linux", nodename="xubuntu", ...}) = 0

BUT when using the persistent storage on the real filesystem (but SAME exact permissions) it fails:

newfstatat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3", {st_mode=S_IFDIR|0775, st_size=4096, ...}, 0) = 0 newfstatat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3/.parentlock", {st_mode=S_IFREG|0664, st_size=0, ...}, 0) = 0 openat(AT_FDCWD, "/media/xubuntu/sys_n01_home/mozilla/firefox3/.parentlock", O_WRONLY|O_CREAT|O_TRUNC, 0666) = 11 fcntl(11, F_GETLK, {l_type=F_UNLCK, l_whence=SEEK_SET, l_start=0, l_len=0, l_pid=1519466008}) = 0 fcntl(11, F_SETLK, {l_type=F_WRLCK, l_whence=SEEK_SET, l_start=0, l_len=0}) = -1 EACCES (Permission denied) close(11) = 0

Am I doing anything wrong or is this some weird startup issue / race condition in the parentlock management?

Thank you for looking into this.

PS: I can upload the full strace file for both scenarios if needed. Thanks again.

When I select a link in an email, it opens op Edge, rather than Firefox. This just started happening today. I have followed multiple options for making Firefox my default Browser, but nothing seems to work. I am using Windows 11 Home Addition. Thank You!

Sometimes Firefox suddenly closes without warning and loses all my open tabs. When it re-opens, I have to log in again to the tabs. My Firefox is up to date and so is my Windows 10 Home. I have a strong Wi-Fi connection.

I have been trying to logon to my SirusXM account for 30 minutes. I enter the email address for the account and it says it can't find it. Then Find Username link tells me to use the email it can't find. Repeated several times. Even got online with SirusXM chat pop up and they told me to use the email it "can't find". The email is/was typed correctly. The FireFox is the latest update. The OS is Windows 11 (updated) and the hardware is an I9-12900HX, 32 gig laptop. More than adaquate. So on a whim I opened the logon site in Brave and voila got right in. Am I doing something wrong with Firefox?

I have new windows 11 laptop. I added firefox browser & made it my default. It displays a news feed upon starting. I've never seen this on earlier versions. How can I turn it off? I don't want anything displayed except a search box & my bookmarks. If this can't be disabled I will be looking for a different default browser :( Thanks.

I apologize for not knowing where to put this question. I have the latest version of Firefox installed and pinned to my taskbar. When I right-click on the Firefox icon that's pinned to my taskbar a list of things that I've downloaded as well as some other things shows up. Now I understand that I can manually clear these items, but that's a pain. I searched online for an answer and through my researching found that these items are called jump lists. I then searched for a solution for how to disable them and followed the instructions I'd found on a majority of sites that provided a solution. Even after doing this the jump list is still enabled and I don't know where else to go. I have attached two pictures showing the steps I've taken and that the jump list is still active.

How can i edit the color of text from exiting theme .. as the picture i need an easy way make text with another color like red or orange or at least make black border outline white titles more thicker and or bold ..

Some files appeared on my Desktop folder. when i erased them my Tabs and profile got deleted. then when i log in my profile the Files return on the Desktop folder.

my problem is why is this happening?. Firefox was installed on default installation drive, and it has been 8 months or more but only now this is happening.

i don't tweak anything on this browser, just browsing and consuming content.

Dear Team. As always thanks for a great browser... I had a Firefox update come through this morning (through the browser prompt). After installing the update the pc became extremely sluggish. Thought it may need a restart so restarted the pc but pretty much the same issue? Slow, delayed and sluggish.

I checked what was running in the back ground and other than the usual microsoft nonsense and background stuff it showed 30 instances of Firefox running taking up 82% of the memory. I always have one browser with 8 tabs running by default.

I'm running an i7 processor with 8gig of ram which should be more than ample. Any thoughts / ideas would be most welcome. Once again, thanks for the best browser....

AdBlock has not made any updates for Firefox for eleven months. Do they just not care, or has Mozilla rejected them? The internet is terrible enough as it loves to scam all users on all sites.

Help!!! After using this profile to sign in here to ask a question yesterday, upon restarting Firefox today it has deleted my entire login history, cookies and all passwords. However, when I go to recover these, the only default profile I can find when I do an "about:profiles" is one that is five years old.

I can literally no longer access any of the sites I use because al of the logins are gone.

Help! How do I get all my data back? My life is over if I cannot access any of my business sites, emails, Paypal, Amazon accounts or anything.
