I am running version 125.0.3 (64-bit) on Windows 11, and I can't check for updates and have to manually download each new version after given a popup telling me that the latest Firefox update couldn't be installed. I've tried restarting the computer, tried running the Mozilla Maintenance Service, and installing the latest updates for Firefox and Windows 11. Nothing I've tried has worked, and no other help article has helped me thus far.

After a crash earlier today within my 32bit install of Firefox, I upgraded to the 64bit version. Since then I have not been able to play videos from sites that utilize DRM.

I have tried the following:

  1. Check and Uncheck "Play DRM content"
  2. Check for updates while in the addons related page.
  3. Checked my hosts file which is blank
  4. Stopped my AV and attempted to update as well as Enable/Disable Play DRM
  5. Get a 404 when attempting to go to "redirector . gvt1 . com" site.

When I looked in my profile directory, I noted that both the "gmp-gmpopenh264" and "gmp-widevinecdm" directories are empty. I found and downloaded the most recent openh264 dll for windows 64bit. Firefox continues to say "OpenH264 Video Codec provided by Cisco Systems, Inc. will be installed shortly." I have not found the most recent wildevine version so I have not tried to update it manually.

Could there be something squirrelly with my user profile that needs to be rebuilt? (I can export the bookmarks, etc) The 32bit Firefox crashed with no messages while watching a live YouTube stream. I just installed over without uninstalling the previous version. I was afraid of losing my current settings. The crash caused my "previous session" to be lost.

Hello everyone,

I have a very weird behaviour with one of my Apple MacBook Pro M1 (2020) with macOS 13.3.1 and Firefox. After removing Firefox (trash + remainings in /Library and ~/Library), Firefox is gone... until I reboot. It then reinstalls automatically!

One weird thing I see in Disk Utility is an "Apple UDIF read-only compressed (bzip2) Media" that I cannot delete because it's in currently in use (see screen shots attached).

I can also see it in with diskutil list:

/dev/disk5 (disk image):

  #:                       TYPE NAME                    SIZE       IDENTIFIER
  0:     Apple_partition_scheme                        +391.2 MB   disk5
  1:        Apple_partition_map                         32.3 KB    disk5s1
  2:         Apple_Driver_ATAPI                         4.1 KB     disk5s2
  3:                 Apple_HFSX Firefox                 391.1 MB   disk5s3

There is no dmg file attached to it, I have no idea where it comes from.

My question is: how can I uninstall Firefox on this computer?

Thank you for any help, Panda

I upgraded from 126.0.1 to 127 today. Upon update, all my windows are gone. The only way I could access them is to revert to an older profile backup and reinstall 126.0.1.

I tried exporting my session with Tab Session Manager in 126.0.1 and reopen them in 127, but that only restores the last tab of each window (oddly). The json clearly lists 3 windows each with multiple tabs. I tried copying the sessionstore-backups folder, but no dice.

I use debian and firefox-esr.

I have problem right now!

I used firefox version 105.0.1 for short times, then firefox transformed my profile to new version profile, so now I can't back to 102-esr version again, I have this message:

`Your Firefox profile cannot be loaded. It may be missing or inaccessible.`

So i try this command to fix problem

firefox-esr -allow-downgrade

or

firefox-esr --allow-downgrade

But still can't downgrade, So I have to ask could I downgrade? else I have to wait for new esr version?

What's the next firefox-esr version? or release date?

I cannot find this anywhere. As a Topic . I've Reinstalled Firefox several times,and,each time the Browser continues to Import the previous instalations Bookmarks.

Noticed that a small Dialog box pops up stating what is being installed,with 'Importing Previous Bookmarks". Should be an Option on Instalation that handles exactly what is to be described as installed. Supposed there used to be. Since im used to installing w/o 'default settings.

The little check box that denotes 'use old settings,and apps,does nothing.

Have another problem with my Bookmarks. And this is what I need solved Reinstalling Firefox without Importing Previous Bookmarks.

Options for Migrations is not a punn here.

For a long time I've used Firefox on Linux with multiple instances each with their own profile folder. Today when I try to run these instances with separate profile folders I get the following error:

> 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.

Profiles are created like this:

firefox --new-instance --createprofile "PROFILENAME ~/.firefox-PROFILENAME"

They are run like this:

firefox --new-instance --profile "~/.firefox-PROFILENAME"

It seems something has broken with the instance isolation as this is now throwing an error. Additionally I run "createprofile" it doesn't seem to actually create the folder.

Hi there,

i'd like to copy my Firefox profile from PC1 to a new PC2;

Last time i tried this, i ended up with PC2 having the same "name" as PC1 in "Sync". This caused weird sync issues, as the system thought my PC2 was PC1 as vice versa.

So, is it possible to copy my entire profile with all addons/settings, BUT, make "Sync" recognize it as a NEW pc ?


Thank you in advance :-)

Browser is FF Nightly 112.0a, but this is probably a bug in stable FF, too. "Always ask you where to save files" is checked, in preferences. Like title says, the "last download location" is stored, and works for downloading files, and downloading a SINGLE item in Tools\Page Info\Media (Ctrl-I), but if multiple items are selected (in Page Info\Media), folder opened will always default to set location, instead of last download folder.

I have just downloaded firefox from chrome and cannot install it. I have tried the usually uninstall reinstall and restarting my computer but cannot fix it. I have had this issue with other browsers in the past eg opera and brave but gave up on them, however, I really want to switch to firefox so would appreciate your help. For some reason it seems chrome is the only browser I can even open on my laptop (windows 11). Do you know a fix?

When I do the keybind (Control + P) or press the print icon in google apps (google docs, drawings, etc) it automatically downloads a pdf instead of opening the print menu. Chosen solution

Printing on any other site pops up with the printing options. Only on google apps does this happen, including gmail.

This problem is non-existent on Google Chrome and Edge. It does persist on Brave although. Haven't tested any other browsers.

Firefox saves files that I only wanted to open with another application.

I checked the previous solutions in the forum, but they did not work for me. (Windows 11) I changed in system> general > download , applications > the app to open that file type and it works, but besides this Firefox keeps saving the files in the default download folder.

I tried also about:config browser.download.improvements_to_download_panel to false. browser.download.start_downloads_in_tmp_dir change to true No change - still saving copies.

I have been using Firefox 56.0.2 on Windows 7 for years safely. Until yesterday. We had one of those mini powerouts, that caused problems.

My hard drive is failing and Firefox will no longer fully load, it tries bless it, but some FF files must be in the damaged sectors of the hard drive. It then locks the system. Using Chrome works fine. But some logins/passwords/bookmarks had to be changed very recently and are not stored in the chrome browser yet. I hate chrome so use FF as the main browser.

I'm thinking that if I can install a fresh copy of FF 56.0.2 in a separate folder, a separate 2nd copy of FF, and then copy yesterday mornings backed up FF profile (before the crash) I could at least copy over all the bookmarks etc to Chrome so I can have my logins etc back.

This mornings backup failed to backup some FF files, all others were fine. Firefox worked fine yesterday but failed to launch this morning.

Please help save my sanity. I know I have to move to W 10, but cannot on this computer.

I cannot use, update, uninstall, refresh, or reinstall Firefox (and haven't for four or more years). I always get this message: "Firefox is already running, but is not responding. The old Firefox process must be closed to open a new window." But I have (obviously) shut down the computer entirely any number of times in all those years. What can I do? I will be taking college classes and Firefox is one of the few browsers that the college supports.

Macos Ventura:

Greetings,

When I started getting msgs saying my browser was no longer supported, I checked my version. Firefox says i have v115esr and that it is "up to date" - i.e. no update available at this time. I assumed I was getting the brush off from those web sites.

Why did Firefox not bring me up to v124? I get a "download update" probably once a month. It's been giving me a new variation of 115esr all along.

I've now downloaded 124 from your site. What do I need to do so that I stay current in the future? Thanks John
