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.

firefox setup 127.0.2.exe offline installer fails with message about "extraction failed" and popup "file is corrupt".

Windows explorer shows file properties and a signature for mozilla.

Is there a way to manually unpack the .exe? Someplace that issues are logged with more data (which file is corrupt?) There is a progress bar that flashes by part way, then a popup window with the file corrupt message.

(Trying to update to hopefully get rid of some crashes.)

Is there a hash for that .exe I could check?

Is it possible to install Firefox (or at least the profiles) onto an external SSD (i.e., not the C: drive)? If so, how?

Note: this is not about migration/backup/recovery of profiles. Nor is it about where files are downloaded by default.

Windows 11 is consuming nearly all of the C: drive. I badly need to get Firefox (and later Thunderbird) onto my E: drive. I further note that the installer gives no options whatsoever as to the destination drive.

Most of the help I've found on the web is clearly outdated.

Thanks. jt

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.

Symptoms similar to : https://support.mozilla.org/en-US/questions/1446921

I have been trying to solve this for a few days now. I tried to watch Netflix when it said, "Firefox is installing components needed to play the audio or video on this page. Please try again later."

I found out this was due to Widevine not being installed AT ALL on my browser for some reason. The plugins manager has been saying that it will "be installed shortly" for a week now. I already tried toggling DRM off and on multiple times. I already tried using troubleshooting mode. I already checked GMP preferences to make sure nothing relating to Widevine was set to 'false'. I already tried turning off my antivirus long enough to try everything again and still nothing has changed. I do not have any VPNs running either. I am attaching a screenshot of what the browser console shows when I toggle DRM off and on again and try to run Netflix. I am also attaching what the gmp toggles say. Please help me figure out what is wrong!

I have a System 76 laptop running Ubuntu 14.04 LTS. The LTS (Long Term Support) ended years ago with Firefox 66. All of that works fine still. My problem is: 1. The world is telling me to upgrade my browser. 2. Mozilla tells me "Note: If you use your Linux distribution's packaged version of Firefox, you will need to wait for an updated package to be released to its package repository. This article only applies if you installed Firefox manually (without using your distribution's package manager)." 3. There will never be an updated package because LTS has ended. 4. IS THERE A WAY TO MANUALLY INSTALL A NEWER BROWSER LIKE FIREFOX 123?

I have been able to manually install the latest version by installing it over the top of my current install, how can I fix the error to be sure that my browser will auto update?

Thanks

Hi there,

On the 23. of Mai I first noticed that I am unable to download any files whatsoever. I tried downloading .exe files and also a .csv file. When I try to download one of these files it appears in the downloads window but immediately goes to the status "Failed". Any retry fails as well.

The same thing goes for extensions. I cannot download any extensions or plugins using my Firefox browser. Since I reinstalled Firefox I can now also not use Plex because Firefox can't install the required plugins.

I will attach screenshots of all the errors I get.

All of the above worked when I tried it on the Edge browser.

Firefox version: 126.0 Windows 11

Things I have tried to fix the issue:

  • Use the network connection from my phone instead of my home network
  • Disable firewall and windows defender
  • Reinstall Firefox
  • Refresh Firefox
  • Downgrade to version 125.0.1 and 122.0
  • Reset router to factory settings
  • Flush dns
  • Restart PC
  • Manually delete profile folder
  • Delete temp files
  • Change download destination
  • Disable "Block dangerous and deceptive content"
  • Troubleshoot Mode

Is Firefox using some other temporary folder for downloads?

Any ideas on how to fix this issue would be appreciated.

Thank you.

Hello,

James here. I CAN NOT find the Firefox application file location. There is no option to show file path upon right click of the desktop icon and I can not locate it in File Explorer. I have done an entire (C:) drive search and turned up nothing. C:\Users\(username)\AppData\Local\Mozilla Firefox does not exist in my file system. I am at a loss here and it's driving me bonkers!
