I am running Windows 11 and the latest version of Firefox. Firefox was working perfectly yesterday, but today when I tried to open it, I got the message "This app can't run on your PC". What could be the problem and how do I fix it?

Thanks,

David

I just updated Firefox only because I got an email saying my version would no longer be supported. EVERY TIME I update something goes wrong. This time the SEARCH field on my address bar disappeared--I can't do searches. HOW DO I FIX THIS? ALways next to the address was a place for inputting searches--WHY would you disappear this? Also WHY is the pointer so large I can't read text underneath when I roll over icons?

I see a number of mail and archived files in my Profile on C drive but they do not come up when I open the program using that profile. How do I get them to be included in the program on startup?

Most of the extensions and applications do not work (VPN...), although they also function on other browsers. Moreover, I see that other FireFox users use them, but for me they don’t even respond to opening. And I don't know who to turn to. My language is Russian. I do translation in Google. I apologize for bad English. But I will be grateful if someday I receive an answer. Example vpn-1click with an empty square. The other did not respond to pressing the power button. The third one simply had a black background. I can’t understand what’s happening. And I need help.

I am unable to replace Microsoft Edge with Firefox as default browser in windows 10. Found solutions do not work. Microsoft Edge is locked in & cannot be moved or deleted. Firefox browser opens but most searches are by Edge. After much effort I finally got Firefox listed as a default app but again must searches are by Edge.

Hi Folks,

nightmare scenario: backed up entire Ubuntu 22.04 system (but failed to copy Thunderbird profile separately): upgraded Ubuntu to 24.04; upgrade failed because Thunderbird Snap upgrade failed. Apparently this is very common, and many other people have had similar problems.

So now I'm working in Recovery mode, root prompt command line.

There is still a /home/username/.thunderbird/profile.default directory. It contains lots of files and directories, including a 5Mb Mail directory. So it looks as though my original mail data still exists. Fingers crossed, prayers etc.

And here's the question: is the directory structure under the new Snap profile the same as the old Thunderbird structure? In other words, can I copy the existing profile, scrap Thunderbird, finish the Ubuntu upgrade, and copy the files back under the new Snap profile?

Thank you for reading this far, and I hope someone can help...

Cheers

John M.

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?

I used the camera on my iPhone 8 to download the newest Firefox for my phone, was sent to the app store, where I thought I "got" Firefox, but my browser Safari or Firefox--I can't tell which browser I use-- on my phone doesn't work anymore, what happened? Thank you.
