Firefox Community Forum

My pinned tabs are showing on the "List all tabs" again.

I previously had this issue and it was resolved by community support by this suggestion.

"You can set browser.tabs.tabmanager.enabled = false on the about:config page to revert the "List all tabs" button to its previous behavior."

I went through these steps again, but the setting is still set to "false" so there must be a different problem?

Please advise how this can be corrected.

I did notice the NEW ICON used on the tabs bar for the "List all tabs." Perhaps this update change caused the issue?

These pinned tabs are extremely helpful in managing my business platforms. I accidentally closed some because I did not realize I was closing my pinned tabs. I wish we had 2 rows for pinned tabs:)

Thanks for your assistance!

The update two days ago has left me with an error message: Platform version '131.0' is not compatible with MinVersions and MaxVersions 130.0.1

What can I do? This is the 3rd update corruption within the last 6 weeks - last time I was told to remove Firefox and install from new so lost at least 6 years history.

I installed firefox v130 from the tar.gz file to /opt. I use the latest enlightenment desktop on debian trixie. Firefox works great, I have no problems with it's functionality.

Unfortunately, I don't like the fact that it uses it's own window manager. When I install firefox from the debian repos (firefox-esr/testing,now 115.15.0esr-1) it uses the default window manager (enlightenment in this case). How can I get firefox to use the desktop window manager?

TIA

When I tried to start Firefox it started an automatic update - like it has many times before. But I then got an error message referring to 'entry point not found' . I have used Firefox for many years without any problems.

Hello Firefox community,

I’m currently working on a project where I need to programmatically configure the FoxyProxy extension in Firefox every time I launch the browser. My goal is to dynamically set proxy configurations (e.g., IP, port, username, and password) before or during the browser startup.

I’ve explored several approaches, but I’ve run into challenges with each method

Does anyone know of a more effective way to achieve this? Any guidance on modifying FoxyProxy settings on launch or programmatically managing Firefox extensions in general would be greatly appreciated!

Thank you for your help!

I have version 130.0.1. I keep getting popups prompting me to update. I'm skeptical at popups so I go to check what is the latest version at Mozilla.com. They don't display that; they only want to automate an update. I won't do that. I want to see what is being updated and to what version before I download and execute some unknown automated process. Mozilla should know better than try to cloak an update on us. We are the ones that use Mozilla because of all the "automated" trouble and hijacks out there.

I have an eTrade account and for the past 3 or 4 weeks, I always have to clear cache in Firefox in order to be presented with the login window. The url that comes up when I launch eTrade is: https://us.etrade.com/home/welcome-back. Once I finish with that eTrade session, I log out but the next time I try to launch eTrade, it just spins. Down in the left corner of my screen I see "Read c.evidon.com" but the login screen never comes up and the tab that I launch on is just showing a spin and never seems to time out. Once I go into settings and clear cache, it works (have to close down firefox and relaunch it though). Did something change in the last firefox update that could have caused this. Never had this issue before and I've had firefox and the eTrade brokerage account for many years.

Yesterday, I installed whatever the current version is for Windows 11. At some point after that, it hung. It wouldn't close, even after doing End Task in task manager, nor shutting down the PC.

When I try to start it, it tells me "Firefox is already running, but not responding. The old Firefox process must be closed to open a new window."

Go to task manager, but the only thing I see related to Firefox is under Details pane. Shows a PID but I can't kill it even using the taskkill command as admin:

C:\Windows\System32>taskkill /im "firefox.exe" /t /f SUCCESS: The process with PID 24344 (child process of PID 19568) has been terminated. SUCCESS: The process with PID 15724 (child process of PID 19568) has been terminated. ERROR: The process with PID 32008 (child process of PID 8260) could not be terminated. Reason: There is no running instance of the task. SUCCESS: The process with PID 19568 (child process of PID 20576) has been terminated.

The PID noted above shows a location of C:\Program Files\Mozilla Firefox\tobedeleted, but if I try to delete it (or any other tmp files with yesterday's date), it says they're open in Firefox and won't let me.

Attempted uninstall and reinstall. Same issues as above. Firefox is now unable to be used. I have a ton of bookmarks that I haven't backed up recently by the way. I do NOT want to lose them.

FF Settings menu, select, Startup, (Open previous Windows /tabs) is greyed out an not selectable. I adopted FireFox because I like the way that it operated. I could open FireFox and previous tabs and windows would open automatically. When I opened a new tab, FF would jump there automatically. If I wanted to check spelling, I could type in the search window and see correct options. ALL THAT IS GONE! Why should I keep using FF when it has lost functions that I depended upon?

Firefox was working all day. Then when I went back to it later in the day, it would not start saying that it couldn't find a dll.

The instructions I found onsite, using another browser was to uninstall Firefox and do a clean install. They instructions said that I would not lose my bookmarks.

I faithfully followed the instructions and uninstalled the application, it had problems doing that as it kept coming up that it could not find a file. However, it did complete.

I then reinstalled Firefox.

I have no bookmarks to anythings. No banking bookmarks, no entertainment bookmarks... no nothings.

It will take me months to recover if I can even find those sites again....

I'm really annoyed with Mozilla and am now seriously considering a new primary browser. In all my years on a computer I have never had this happen before.

Now if you know a way that I can recover all my bookmarks, I will reconsider.

Since Mozilla Firefox web browser v127.0 (released June 11 2024) the manual installation of the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) do not work anymore!  :disappointed_face:

So, when you go in any higher version of Mozilla Firefox web browser then v126.0.1 (released May 28, 2024) to this web browser Menu Bar -> Tools -> Add-ons and Themes -> Extensions -> Install Add-on From File..., and then try to manually import-install the Adobe Acrobat Pro extension (the adobe_acrobat-1.0-windows.xpi file) into the Mozilla Firefox web browser, and from this HDD location:

C:\Program Files (x86)\Adobe\Acrobat DC\Acrobat\Browser\WCFirefoxExtn\WebExtn\signed_extn\adobe_acrobat-1.0-windows.xpi

The Mozilla Firefox web browser will say during this .xpi file installation: "This add on could not be installed because it appears to be corrupt"!  :disappointed_face:

However, in any Mozilla Firefox web browser version prior v127.0 (released June 11 2024), this manual import-installation of the adobe_acrobat-1.0-windows.xpi file will be most successfully installed in a Mozilla Firefox web browser without any problem!

I also create the most detailed and step-by-step post on the Mozillazine.org Forum and the Adobe Forum about all of this problem:

So, please help and advice further. Thank you in advance and best regards!

Mozilla Update appears to have a bug. I have several Windows 10 or 11 PCs with Firefox, and nearly all have the same problem. My event log is loaded with Event ID 16398, saying "A new BITS job could not be created." When I run the Get-BitTransfer command, I see the queue is filled with MozillaUpdate transfers. I have to execute "Get-BitsTransfer | Remove-BitsTransfer" to clear them out.

I can't find anything on the web to stop this, or even acknowledge it is happening to others.

I just updated Firefox on my Mac. Subsequently when I tried to restart Firefox the OS thinks a copy is already running in a display and closes startup request down. I am unable to use Firefox at all at the moment. Can this be fixed? Cheers John Spitzer

I worked for a lot of time of some splendid webgl animation on a laptop gbl file in threejs that renders a video on screen texture and it worked fine untill firefox did some updates and videos in laptop screen is glitchy, if i disable hardware acceleration it works, BUT firefox comes with it enabled by default and when clients come into my page see that ugly effect of the video, AND no there is not video drivers problem, my drivers are the latest and i tryed on different devices same thing, i thought that there are some problems with my domain checked and triple checked and no, with an older version of firefox it works perfectly, i tryed looking on other people webgl with video on it to see maybe i have a problem on my code and its same thing, no cors problems, drivers, or how video is coded, i loved firefox im using it for years but now i hate it so much cause it ruined months of work

Dear All,

I need to uninstall Firefox silently from several computers, due to company restrictions. Uninstall must be silent (automatic), because I push the uninstall from Microsoft InTune.

At this stage, using "-ms" or "/S", I can bypass the normal uninstaller prompt, but I still get a Windows warning (from User Access Control), asking autorisation to perform changes on the device.

Can I bypass this prompt as well, so that the uninstall is indeed automatic and silent?

Alternatively do you know of means to modify this at Windows level?

Many thanks!
