Firefox Support Forum

Today when I close many tabs using control w firefox seems to randomly jump around when choosing which next tab to close

I wish to have firefox always close the adjacent tab to the tab I just closed

This should be the default behavior ... I do not see any setting for this ... is there an addon to do this ?

I am using the latest firefox on ubuntu

• • • UPDATE*** below answer for setting `browser.tabs.selectOwnerOnClose` has no impact on this

After updating to Beta 122.0b3 (64-bit), the active tab is now highlighted with a simple white outline instead of the coloring surrounding the address bar. My selected theme has not changed, and the same goes for all of my extensions. I could not find this change in the 122.0b Release Notes.

If this behavior is intentional, is there any option to return to the previous behavior (including in about:config)?

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.

DEAR SIR MAM PLZZ HAVE A LOOK

Добрый день! Почему не меняется язык на английский? Как его сменить?! Только не надо мне писать про удаление кук и чистку кэша! Я только что это сделала потому что не работал чёртов логин в чёртов акканут чёртова твича!

Any method I open a new tab, it always takes up to 7s to load, while completely suspending my browser. This also happens in troubleshoot mode but not in incognito. Directly opening websites in a new tab doesn't trigger that bug. I don't recall when this started to happen, it might be after some new Windows update.

I have included screenshots from Firefox Profiler, both from regular window and incognito one.

It worked nicely for many years, until today. I installed Supraland from Steam, played for a couple of hours, and suddenly my Youtube page went glitchy - not the layout but minor elements were getting scrambled, especially text. I'll attach a couple of pictures to show it. In fact, all pages glitch if their content changes even a little. As of typing now, I see the glitches, with a word or another getting butchered. Gifs and videos are full of that.

Windows 10, the current update, Radeon RX 580, the recommended AMD drivers installed (and reinstalled again and again, 23.11.1)

I think I did pretty much everything with Firefox. Disabling hardware acceleration fixes it (but then of course the browser goes slow). Games work fine, including Talos Principle 2 which is intense enough. The clean install, reinstall and all that. I'm writing from the beta stable build now. I've tried to regress to the previous versions too.

It strictly coincides with the game installation but I have no close backups - who knew that some game might just do that. Then, of course, I tried to uninstall it too.

Thoughts?

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.

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

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.

Attempting to log-in on Twitch with Firefox Browser - Developer version 122.0b9 (64-bit) is currently not possible, repeated messages are prompted by the Twitch website about "unsupported browser" and to contact browser support to resolve this issue.

Clearing cache, disabling extensions did not work. Using regular Firefox works without issues, only noticed this being an issue after most recent update for Firefox Dev browser.

Side effect as well since update is that any Cloudflare captcha is impossible and all website that use Cloudflare to "authenticate" that I'm human just outright fail or continue indefinitely.

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 all,

I'm wondering where sent tabs go before they arrive at the destination browser instance? Snoozes tabs go to a bookmark, but what about sent ones?

The reason I ask is because my Firefox instance, oddly, created itself a new profile one day. I don't know why, I didn't ask it to (as far as I recall), I only noticed because when I wanted to send tabs from my phone to my desktop I noticed I had a new "so-and-so's Firefox on xyz computer" appear, then on inspection I realised that my old profile has been mothballed by Firefox. When I loaded up the old profile it no longer had the browser name that I'd previously given it in Firefox Sync settings, and the tabs I'd previously sent to it did not appear. Whilst I'd like to understand why all this happened, it's not critical to my question, I just provide it as background.

So, where do these tabs go? If they never arrive at their destination then where can I find them again?

Cheers :)

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.

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.

Subject says it all, but it seems to occur with any site, anytime I try to open more than three or four tabs (ctrl-clicking links on a forum, for example) my Firefox instance grinds to a halt and starts consuming most of my CPU (Ryzen 5 3600).

I've tried turning off Firefox's various protections. I tried troubleshooting (formerly "safe") mode, and the problem isn't as bad but is still present as far as I can tell. The only extension I can think that would be making it worse is Tree Style Tab, but I don't know enough about interpreting Firefox profiles to verify.

The only reason I consider this odd is because doing the same thing in Chrome doesn't have this issue on this same device. If I open many tabs quickly, Chrome itself is still responsive. Those newly opened tabs may take a while to load and become interactive, but it doesn't affect the rest of the application. I pay my ISP for gigabit DSL, and as far as I can tell that is roughly what I get. In my case, Firefox doesn't behave this way.

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?

MS Edge works just fine.

When trying to set up alert notifications for FEDEX tracking status, the Submit Button remains active, even after filling all required fields and checking all required boxes. See website:

https://www.fedex.com/fedextrack/?trknbr=270004161734&trkqual=12027~270004161734~FDEG&trkcarr=FDXG&gsu=true

I have set https://www.fedex.com/ as a trusted site (Exceptions), and turned off Browser Guard. Also placed same URL in MalwareBytes allow list.

Firefox is the default browser on my MAC… used it for years, no problems.

Lately, when I get my daily email from The Washington Post, and I click on a link to an article, Firefox (1) shows me the lead picture as a blur and (2) in a short time, blanks the window.

When I click on “reload,” the article comes back (at the beginning of the piece) with the same fuzzy picture and again, within a minute, blanks the window.

If I use the same links, from the WashPost article, and use Safari, the pictures are clear and the article doesn’t disappear.

I don’t know if it’s related, but when I’m playing a game from the AARP website, and it’s time for a commercial, the window goes blank and I have to reload … which brings up my game where I left off.

I don’t know if it’s relevant, but I have “AdBlock Plus” and “AdBlocker Ultimate.”

Any thoughts ???
