Firefox supportforum

Over the past few weeks I've been unable to watch live videos on Firefox on Ubuntu 22.04. I thought it was just an issue with Twitch but I realized the problem also persists on live videos on Youtube and did some troubleshooting which didn't solve the issue. The only solution I was able to find for Ubuntu said to install ffmpeg, which I already had, but I made sure it was upgraded, refreshed Firefox, and still have the issue. Currently I'm on Firefox 121.0 but I've had this issue since before I updated it. I dual boot Ubuntu and Windows and am not having this issue when I boot Windows on the same computer and Firefox profile.

When I click the address bar, Firefox lists favorite sites. How do I disable this list until after I've typed?

I don't want the list because I don't want to be distracted by these sites.

While they are safe-for-work, I'd rather "fun" sites didn't come up when I'm working with other people.

I am working on a website that uses Unicode extensively. Some glyphs do not show correctly. In particular U+2A75, which is double equals. I am using Ubuntu, and I have installed Unifont. In the image, I have opened Firefox on the right and Chromium on the left, the URL is https://www.compart.com/en/unicode/U+2A75 Chromium is displaying the page correctly, Firefox is not. However, in both cases, the character is correctly displayed in the text in the Tab header after the favicon. browser.display.use_document_fonts is set to 1 I have read the Support page on editing fonts. Inspecting the element as suggested in the 'Editing Fonts' page, (see 2nd image uploaded), I see - in the source pane on the left, the character is correctly displayed (as in the tab text) - the Font being used to display the character in the rendered HTML is 'Source Sans Pro', which probably does not have the glyph for U+2A75. - the Font supplied by the website (presumably it does have the glyph) is list as a font, but I can't find a way to have it display the element.

I have tried to change the font family for the selected element in the Rules pane, but that does not work.

I have tried a variety of other changes in about:config but nothing seems to work.

I have two thoughts - the Font family for some Unicode ranges may be set for security reasons, and so U+2A75 is forced to some other Font - the fallback mechanism is not working to select a font when the glyph is not in the first family.

When I open a new tab in FF, a row of 8 boxes appears below the search bar where I can add shortcuts. I currently only use 5 of them, meaning there are 3 empty boxes left over. I don't want to have them show history, or recommended websites, or anything of the sort that might distract me; the shortcuts should only be those I actually intend to use, of which there are only 5. To my knowledge, the only easy way to add/remove shortcuts is to adjust the number of visible rows, but this only allows modifications based on multiples of the original 8. Like in Chrome, can I actually remove any excess shortcut boxes I don't want to use? I feel this is a very basic customization I'm sure Firefox should be able to accommodate.

I've included a screenshot of my FF new tab, where the three empty shortcut boxes I'm referring to can be seen. Thank you in advance for any assistance!

Im trying to halt fingerprint tracking, whoever designed Firefox's privacy.resistFingerprinting rule makes fingerprinting even more prevalent.

With privacy.resistFingerprinting set to FALSE, my resolution is reported : 1920x1080x24, set to TRUE its 1920x968x24

1 in 6 browsers has resolution 1920x1080x24 1 in 6000 browsers has resolution 1920x968x24

Who in Firefox decided this config rule? and what is the logic behind it? Looks like intentional sabotage to make peoples browsers more trackable.

Whilst leaving resistFingerprinting set to TRUE, How can I force my resolution to the more generic 1920x1080x24?

Is there another setting in about:config I can change? if there isnt, where can I request this feature? Id rather not resort to an extention for something so small like this.

I fill out a specific online form on a regular basis. When I used Chrome several months ago it always remembered my form data. But no matter what setting I set I cannot get this to work on Firefox.

Under Privacy & Security I've set History to Use custom settings for history: Remember browsing and download history enabled Remember search and form history enabled Clear history when Firefox closes disabled

I have also checked antivirus, antispyware, firewall, and privacy programs are not interfering. I do have a VPN but only use this when using online banking.

After using gnome-tweaks to change my system fonts, Firefox has unexpectedly gone silent and no longer shows text in areas like the search bar, tabs, settings, bookmarks, and menus. Rendering websites works just fine, but Firefox itself won't show any text.

I just upgrade my firefox, but it did not import my history, cookies, bookmarks or passwords. I found a backup of the bookmarks (in a bookmarkbackups folder) but how do I restore the everything else?

Hi Just updated Linux Mint from 20.3 to vs 21. Firefox Help now shows FF version Mint - 001-1.0 121.0.1

Also shows that FF updates disabled by Administrator.

Is this the latest version for LM 21 ? And how do I enable updates automatically?

Thanks

I have constantly crashing tabs with FF 121.0.1 32-bit on Debian (happening since at least 120, and probably 114 or perhaps 115 ESR), and about:crashes has no listing of any tab crash reports; this hasn't been an issue until the most recent version. I'd like to report them so that they could hopefully be fixed, but reporting doesn't seem to be happening? Thanks.

i use firefox on ubuntu and a dropdown terminal app called tilda. i configured the F1 key in the system to bring down the tilda terminal. it works in every other application, just when firefox is in front, the F1 key does nothing. it wasn't the case before, now it is.

I use Duck duck go as my default search engine. I've noticed that after the last couple of updates, the default has changed to Google. This has not happened before. There must be a bug somewhere that is causing this to happen in the new version of Firefox.

The Debian Firefox packages available are only 115.6. Thought it would be nice to have the latest. Grabbed all the dependencies according to the Mozilla web site.

Installed Firefox 121.0 as root and placed folder into /opt, as instructed. Went through all the settings and imported my bookmarks.

Now there is a 121.0.1 upgrade available but my browser won't automagically install the upgrade. Says click here to download. So I do. I get the entire tar.bz2 bundle, which creates a full directory structure, as if I was starting over.

Can I just move a few files from that into the existing /opt/firefox directory to get the upgrade? If so, which ones?

Or, can I move few files from the existing directory into the new version, and replace the whole lot? If so, which ones?

Thanks in advance.

The title describes the problem I'm facing. I don't really use other sites that have videos other than Youtube. But I notice that the videos freeze quite often and audio just continues to play. The videos then unfreeze and skip multiple frames. I've noticed clearing browser cache seems to help but it doesn't help for longer than a 2 min video at best. At worst, it doesn't affect it at all.

cannot download firefox browser because I have an expired chrome browser that I'm supposed to delete first -

However - have tried a dozen or so ways to do just that - or so it appears and still cannot download the

firefox browser and after much frustrated key pounding find evidence chrome is not really deleted - help losing

my mind - I'm 77 years old and not computer literate but not senile either - i hope

Hello, this is a problem I've been dealing with for nearly 2 months now. Currently using Linux Mint Cinnamon

The browser won't connect to any websites or even try to load them, anytime I search for something it immediately goes to the error page. I've been struggling with internet on my PC for months and all was fixed when I hooked up ethernet, except for Firefox.

I've gone into about:config countless times. I've restarted it twice, I've tried installing the flatpak version and it's exactly the same result. I've deleted it and reinstalled, nothing. I've unchecked everything I've changed in about:config, once again nothing.

I can't update it as for some reason it says it's disabled by system administrator, which I don't remember enabling. I checked the firewall and it's perfectly fine. No infections were found when I scanned as well.

It's starting to become frustrating and I can't even do anything on my PC because it's acting up. Any and all help is more than appreciated and welcome. Thank you.

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.

Hi experts,

Recently, I couldn't log in the Globus through Mozilla Firefox browser where I usually log in the Globus successfully. It just stopped and nothing happened. Could you please let me know how to address this issue? If you need any other information from me, please feel free to reach out to me.

Thanks, Jian
