On Mac OS 14.4 Firefox hangs on launch and crashes, requiring "Force Quit" when I try to Refresh or Troubleshoot. Uninstalled and reinstalled multiple times, and restarted computer several times. Have spent several hours trying multiple community suggestions to now avail.

I am not a programmer, but am able to follow instructions. I clearly need someone to hold my hand and walk me through the solution. (I even checked out the Kaspersky suggestion, but cannot install it because Firefox cannot connect to the Internet.)

I have downloaded and saved "Raw Data.docx" and "Application Basics tex.docx" from one of the crash reports.

P.S. On this question form Firefox guessed that my operation system was Mac OS x 10_15_7, but it is 14.4

I was advised to use the Authenticator.cc extension for my Firefox browser on Windows 10 PC, I can't get it to run. It downloads but will not then do anything. I can't get the icon into the menu bar, I can't scan a QR code, it just will not perform. Why not?

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!

Hi guys.

Need some help. I can't download any files using Firefox. It always says, "Failed".

I tried other browsers, and I'm able to download just fine.

I already tried this guide, https://support.mozilla.org/en-US/kb/cant-download-or-save-files, but still same.

I haven't tried to re-install Firefox because I have a bunch of workbook marks that might get lost. So, I want the re-install option as a last resort.

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.

No idea what the cause is but I cannot download ANYTHING on my browser for some reason. Pictures, documents, executables, browser extensions. Tried downloading documents from email attachment.. fail Tried downloading VLC... fail Tried every default recommended solution, clean install, you name it. Mind you all of these files downloaded just fine perfectly via Microsoft Edge.

Noticed another abnormality. Changed the download folder to a custom one. Download failed and DELETED the folder for some reason.

I usually download and install manually the custom install of Firefox on Windows.

Recently, a new version was automatically installed without my permission and destroyed all my customization. THIS IS UNACCEPTABLE. I had to restore the older version from backup and I was going to stop updating.

But I see that the manual custom installation is still available for download.

I want to make sure that if I use it it will not wipe out my customization again.

Please confirm.

While following this step in order to reduce CPU and memory consumption of firefox [content-prefs.sqlite file], I accidently deleted the Profile folder itself.

After this firefox wasn't opening and was stuck on not responding in activity monitor.

I reinstalled firefox, multiple times even after a shutdown, removing any old files in the Library folder. Still it's stuck on the same issue, firefox doesn't opens up even once.

I am in the process of migrating to a new Windows 11 PC. I am a long-time user of Firefox and have version 126.0 - 64 bit on my old PC. On my new PC I apparently downloaded it from the Microsoft Store during all my software installs. That version shows as "Windows MSIX Package Mozilla – MSIX – 1.0”

Are there differences between the 2 versions and should I do anything such as reinstalling from Mozilla?

Thanks, BillT

I need to migrate the complete profile (all settings, bookmarks, passwords etc) from a snap install to an apt install on the same system. Currently I have both versions installed, but i want to remove the abomination that is snap..

I tried copying ~/snap/firefox/common/.mozilla/firefox files to ~/.mozilla/firefox but that doesnt seem to work. Since this is a multi-user system i dont want to rely on mozilla accounts to sync everything to the cloud.

What do i need to do in order to migrate all the data from one install to another?
