Firefox Support Forum

Hey folks, I use the firefox developer edition and I downloaded a zip file in it's private and when the download was complete I closed the window and open the download folder but the file was not there I haven't change the downloads folder location

I switched from windows 10 to 11 and to a new laptop. Here in my new laptop Asus tuf 15 ,even though it has better RAM , internet connection, cache memory, cores the FIREFOX doesnot function properly. It's extremly laggy specially when I use YOURUBE . In my earlier HP laptop with 8 GB ram I could use 10-15 tabs at one time .It would still not lag . It could do web development at the same time I could watch youtube tutorials. But now I barely open 4-5 tabs the youtube starts freezing up to the extent that I really get frustrated. Please so something or I will have to switch to BRAVE browser or something.

Hello,

I use the Firefox browser on my phone and laptop, and have Lockwise on my phone where all the passwords are stored. Until yesterday, all these passwords would always appear in my Firefox browser stored passwords. Now, they only show up in Lockwise on my phone and do not show up in the phone or Laptop Firefox browser.

I have followed this guide: https://support.mozilla.org/en-US/kb/end-of-support-firefox-lockwise and am syncing passwords across devices, but this did not solve the problem.

Has anyone else encountered this and know how to fix it?

Thank you.

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.

I change nothing in my settings and I am now on Dark background everywhere despite having: - forced the system settings (OS) to stay in light background - in about:preferences appearance I've manually selected (forced) the light background - in about:config I've tried to switch the browser.theme.content-theme to "1" (instead of "0")

this is really frustrating, I would like to get a better "reading" of what happens, as an Engineer I am happy to also squint at logs if needed, please consider adding a preference / settings change log file

I'm experiencing a problem when I visit certain websites, like 'https://mui.com/x/react-data-grid/'. Every time I try to access this site, the page starts an infinite reloading loop, preventing me from using the website normally.

No crash report, no trace, no anything. I click "Save [insert] as...", and Firefox hangs and stops responding. Windows automatically shuts it off when clicking. Launching Firefox again sometimes says there was a problem reloading the session, but that's not guaranteed.

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.

     running on an xubuntu distribution "22.04.2 LTS (Jammy Jellyfish)"

"Your browser is being managed by your organization" is on the top of my settings page and it preventing me from using some of my streaming services. I am at my home, don't work at a job where I would ever be on a network, what the heck? It is some name I don't even know. Did I get hacked? Is it a virus? Nothing I have seen on here so far has worked, and I AM NOT A LINUX USER. (After looking at other answers, seems to be a problem with Linux.) I am on Windows 11. Thanks!

Dear community,

since some recent update I am asked for a primary password every time I open the browser, which is higly annoying. I like my passwords protected by a primary password and in former times it was only asked for when trying to reveal a saved password. I know this has probably to do with me using Firefox sync, because I use the browser on my Android too but I would like to keep my devices synced. Besides: On my phone I am only asked for a fingerprint when accessing passwords, not every single time I open the app. There must be a way to reconfigure this on a desktop, right?

above site is not opening in Firefox but it is opening in Chrome easily! What is the problem

Yes I have tried everything that has been written or suggested on how to fix the fixup. Still nothing has worked. About:config everything has been set to false that has been suggested. It seems this latest version wants to eliminate our ability to customize and you even know how dangerous this is.

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.

I'm getting locked out of a site I visit regularly. Their tech support sent me this reason:

‘Firefox browser (or some extension) is sending multiple requests to us with the browser User-agent "Mozilla/5.0 (compatible; Googlebot/2.1; +http://www.google.com/bot.html)"' This can't be happening from the normal usage, so we automatically block them because they are not the requests from genuine Googlebot crawler.

The possible cause might be using some browser extension that makes the request with Googlebot user agent.
Please make sure to disable all extensions (and remove that you are no longer using) and let me know so we could check on our end if that stopped?"

How do I find what is doing this and how can I fix it?
