I received an error indicating that Firefox was unable to be updated. I tried refreshing the installation as suggested, to no avail. Then I removed the application, downloaded the most recent version, and tried to install it. The installation never seemed to begin. I tried troubleshooting compatibility again with no success.

I've rebooted between each failed attempt to install (at least twice). I opened Task Manager, and the process appears to be stalled. It starts; however, it doesn't consume any resources and hangs. I've attached a screenshot of basic system information.

I use Firefox as my default browser; I would really like to get the newest version installed on this device. Thank you, Aluca Lindstrom

I’ve had the Firefox app on my iPhone 15 and have used it many times as the search engine. I noticed now when I try to use it as a search engine it seems to be hijacked by DuckDuckGo as that is the search engine. Past searches would give me a Shortcuts to where I wanted to go but now all that’s gone. Trying to download it again it will not download

This was a WIN 10 but has been professionally upgraded to 11 two times with last just a week ago. I have run Firefox as chose browser for years. Now they keep bumping me off & back on Google. Have tried to ID Firefox as chosen but they don't seem to hear. Even with Firefox symbol on my screen, now I click on it and Google comes up. 

 Have tried downloading again without success.  Ff will not show up in a Program search.

What to do?????
