For the last few days, Firefox is being removed from my computer overnight and i have to re-intall the browser the next morning. Sometimes it's still there the next day, and sometimes it's gone again the next day. What i causing this and how can i prevent it from being removed? Jenny

Hi, I have had many successful years using Firefox until 4 days ago. I uninstalled Firefox in order to remedy a recurring missing bookmarks issue.

• I used the 'full' version to re-install - install proceeded to around 50% then crashed my system.
• I uninstalled the remnants and tried to install using the 'stub' installer, it crashed immediately
• I uninstalled all anti-virus software, this time the full installer ran all the way through but when I clicked on Launch Firefox, my system crashed again.
• After each crash, the system restarted and remains stable, nothing else appears to be affected.
• Basic diagnostics, returns no violations
• Each crash returns - stop code: Critical_process_died (0xEF)
• my Win 11 version 24H2 osb 26100.7462, FireFox version 146

any ideas ?

They come in as Unconfirmed ######.crdownload I've tried the link on the Mozilla site and the link in the Microsoft store. I'm using Chrome as a browser & want to change.

I'm running fedora open access software 64 bit. when I hit download firefox the computer runs it and it seems like it does it but I can't find it in downloads and it basically doesn't complete. What to do?

It appears my Firefox system is operating under Windows 10, which creates an issue with my email because, currently I'm running the Windows 11 operating system!!!?

  Is there a solution to this Problem?

Due to a technical issue, I've deleted Firefox and re-downloaded it. However, the SHA hash doesn't match. shasum -a 256 [path]/Firefox 134.0.2.dmg shows a hash of:

c87eade89ddf5d1996766840809b5d415d91ecb696326b4f1f92210200978d21

but that hash doesn't show anywhere on https://releases.mozilla.org/pub/firefox/releases/134.0.2/SHA256SUMS

mac/en-US/Firefox 134.0.2.dmg shows a SHA sum of:

7832a8d1e1a13322dec1b52d32e1e64d2b6254de8348575f2d22af4975d56a85

which is completely different.

I re-downloaded it, this time from https://www.mozilla.org/en-US/firefox/all/desktop-release/osx/en-US/, and this time the SHA sum is:

47e1c3b84e79d331842ccf994be56cd423126eaca6acfd1664d668cf48f98de0

which is yet different, and is also not found on https://releases.mozilla.org/pub/firefox/releases/134.0.2/SHA256SUMS

What's going on? Why can't I get a matching SHA sum?

After installing update for Windows 11 23H2, Firefox would run but could not display pages. I tried re-installing Firefox with the online installer but it can't complete the installation and no Firefox.exe can't be found. I then tried downloading and installing the offline version. The installation appears to complete but Firefox doesn't launch and Firefox.Exe can't be found in C:/Program File/Mozilla/.

Hi, I have been experiencing issues lately with Firefox. Attempting to install it often comes up with errors suggesting file corruption but I eventually got it to install. However, now it crashes as soon as I open it and in the past before a system reboot on my PC, Firefox tabs crashed very often. I'm trying to diagnose the issue. I have completely uninstalled and reinstalled Firefox multiple times.

As my laptop is currently experiencing other issues, if there's a specific driver that is causing trouble, it'd be great to figure out what's wrong and what is causing Firefox to not function.

My specs are: Asus Rog Strix G614JIR - (GPU: 4070RTX, CPU: IntelCore i9, SSD 1TB, 32GB RAM).

I have attached the most recent crash. Any help is much appreciated. Thanks.

Hello, I use Windows 10, I downloaded Firefox using Microsoft Edge. Once it is installed, it creates an Icon then when you double click it, it does not open, even when I try to open as administrator and it opens, it does not look like a Firefox page because it is a blank page. My browser is Opera, but I opened Firefox from Microsoft Edge. Email me at [email removed]@yahoo.com please.

Hi, just tried to access Firefox via an existing PC desktop short cut and it said "The item "firefox.exe that this shortcut refers to has been changed or moved, so this shortcut will no longer work properly. Do you want to delete this shortcut?" Not sure why it's suddenly done this.Should I delete the app via "Add remove" and re-install.
