Good evening. Since a few days (since installed ver 124) I'm unable to use the "repeatability" from keyboard. I couldn't find any adjustment option in configuration to manage this. I tried outside (with other programs) and it works fine. Maybe its me, that I'm missing some adjustment. Would you guide me about this, please? Thanks in advance!

I have followed the troubleshooting suggestions with no avail. I am currently in troubleshooting mode with all add-ons disabled. The problem persists. The only way to handle the problem is to depress the scroll wheel on the mouse and start scrolling. However, the problem returns with the next page. The problem shows up on Windows 10 as well as Debian bullseye.

I have used Firefox and Firefox-esr for years on the same platforms. This problem started about six months ago with no resolution. So what has changed? On Win 10 Firefox keeps getting updates whereas Firefox-esr never gets updates. The problem persists on both platforms. More than one mouse has been used with the same results. I have removed Firefox and Firefox-esr and re loaded them, no joy here either.

I have run into an annoyance where I am trying to click on a link in my email to open a new page. Clicking on the link makes a bar show up telling me that Firefox has prevented a popup from being opened (see attached image). I am given the option of managing my preferences / Firefox settings, where I can either go through multiple steps to permanently allow all pop-ups from that website until I restore my original settings, or uncheck a box to permanently allow all pop-ups from all sites until I check that box again. This is annoying because I have no interest in either allowing or disallowing all pop-ups from all websites, or all pop-ups from this specific website, every time I want to open a single pop-up from a specific site. I would rather that the warning bar which tells me that Firefox has blocked a pop-up also display a button allowing me to allow ONLY THIS SPECIFIC POP-UP IN THIS SPECIFIC CASE.

Is this a setting that exists in Firefox? Alternatively, is there a version of Firefox which does have a setting which would allow this? Or is this simply not a functionality that exists for this browser?

Hello, I've got a reproduction issue on France TV live programs which I watch through nordvpn. The picture keeps "jumping" fast up and down in a very bothering way. This doesn't happen when the video is NOT live. I run the latest version of LINUX MINT. What can I do to fix it? The only way I found to stop the issue is to take down the resolution of the live video to its minimum which gives me a disastrous picture but stops the "jumping". I guess you might say there is something wrong with my GPU. The point is that my PC is brand new with an AMD 5600G, new MB, 16Gb of RAM and 500w of PSU. BUT more than anything I have to say that everything WORKS FINE with CHROME. I like FIREFOX I have been using it literally for decades now. (I'm 75). Is there a solution? Looking forward to hearing from you. Thanks in advance. François.

I accidentally hid the menu bar and toolbars (with an accidental keyboard shortcut, I think), and when I re-enabled them, now the tab bar is above the location bar instead of right above the content windows. How do I move it back? I can't find the "browser.tabs.onTop" setting in about:config, or any check box in the View menu, settings, etc.

Firefox does not play videos on after Ubuntu upgrade

A few days ago Ubuntu (22.04 LTS) showed me a message saying I can upgrade my OS (or something along those lines). I click on agree (any button that would let me proceed) and the upgrade took place (without restarting). Along with the upgrade Firefox was also updated to its latest version at the time (119.0). Since then, videos on Twitter play but without sound. On some other websites also none of the videos play. On YouTube, Firefox shows me a message saying "To play video, you may need to install the required video codecs" but the videos play fine; I haven't tried other websites but I assume all would have some issues. Google Chrome however doesn't have this issue and all videos play without any issues.

Note that I have not restarted my computer since the upgrade. I doubt this could be an issue but please let me know if you think this could be the issue.

I did the followings and restarted Firefox but none have worked so far for Twitter and some other random websites that I come across, but they resolved the issue for YouTube and now YouTube videos play, although I still get that codec message at the top of the tab:

sudo apt-get install ffmpeg sudo apt install ubuntu-restricted-extras sudo apt install libavcodec-extra

Someone told me this is because the default Firefox on Ubuntu 22 comes as a snap package and I should install the APT package manually instead so that it works. I prefer not to do this because I have lots of tabs open and have manually changed lots of the settings (including in about:config) that I want to preserve. I would also like to preserve the history of visited websites and keep the current cookies (don't really want to keep entering username/password on the same websites again). So the best way for me is to fix the issue for the default Firefox on Ubuntu 22.

Could you help me figure out what I should do to fix this issue?

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.

Hello everyone. Well, I've been using Firefox for a few months, maybe a semester now, I don't remember. But the point is that since yesterday I have been facing a serious problem of not being able to download any type of file (MP4, PDF, .JSON, ISO, etc.). I've already used the troubleshooting mode and I've also restarted my laptop, but it didn't help. I've also gone to the advanced settings (see 'about:config > browser.download') and reset/deleted the data for each command but the problem still persists.

What happens is the following: I click to download the file in question, however, nothing happens other than the page loading that commonly occurs when downloading something. Still, the file does not appear in the downloads tab and there is not even the option to choose where to save the file (e.g. Downloads folder, Documents folder). The download simply appears to have failed.

Exactly, it 'appears', because today I discovered that all my downloads were being directed without my permission/action to the 'downloads' folder (And that's not where I want them to go). The problem would be smaller if only this happened, as I would then just get the files downloaded there and then change to the desired folder, thus trying to move forward despite the problem. But the downloaded files themselves are not operational, they have the icon when a file is still downloading, in addition to not having a name, everything being just a cluster of codes.

In the end, there are files, large and small, that have no use and that I don't even have control over where to direct them. Which is still a huge problem because I still technically can't download anything from the browser. Please, I really need your help on how to resolve this problem.

Note: Also, when I close and open the browser, the first download I try appears in the downloads tab, but it fails instantly and cannot be resumed, making it an eternal failure.

I used to be able to right click an image and select save as, but now when I right click and select save as I do not get the menu to save in a location on my pc.

Also firebox will not download any files, and also when using my web site's Upload or download a file, this does not work anymore.

They used to work, but I have to use chromium browser to do things in.

Also Firefox will export any files or even my bookmarks.

Been happening for around five weeks now and is impeding my work flow enormously.

Please held.

I have tried all the fixes I can find online without success.

Ps even here where it says add images (optional) it will not open a box to browse my files.

Hi,

This is for https://outlook.live.com where I cannot access my full list of folders. I am using Firefox on Linux (in Fedora 34) and my scrolling feature hasn't been working for a few days now. When I search for an email in one of the inaccessible folders, the folder does appear.

Any suggestions on how to fix this?

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.
