Windows 10: Firefox unable to complete re-install....

Having had problems earlier with Firefox my default browser decided to remove and re-install, however the new download is unable to complete saying try again. This sounds as though it hasn't uninstalled properly to begin with so any ideas how to resolve this ?

Thanks *Smile

:)

 

Windows 10 Creators Update v1703 Breaks Internet Shortcuts and opening local *.htm & *.html files !!!

Think I would uninstall completely FireFox and after a restart re-install it.

You didn't mention if 'Edge & IE' browsers still work ? local .htm work in those here for me.

 

Edge and Chrome start normally; Firefox requires "Run as Admin"

Victor_W, I've tried to start the Firefox Profile Manager several times; all I get is "This app has been blocked by your system administrator." I've refreshed Firefox twice, re-installing my extensions manually. (I didn't install them all, just those
I remembered offhand.) I still get the same problem. As a last resort, I'm going to completely un install Firefox and delete all its files, the download and reinstall it again. I hope this works.

 

Copy and paste: %APPDATA% To file explorer address box then hit enter. Is there "Mozilla" folder existed ? If so, navigate to
Firefox\Profiles\xxxxxx.default where xxxxxx is a random character pattern.
and save places.sqlite to somewhere else, this is your bookmarks.

Go back and delete "Mozilla" folder then try to re-install Firefox. Once done, replace places.sqlite to get your bookmark back.

NOTE: if you have created a Firefox account then you will not have to replace places.sqlite.

 

Thanks no mention of Firefox at all....

 

did you navigate to
C:\Users\YOURUSER\AppData\Roaming\Mozilla\Firefox

 

Yes removed all mozilla/firefox entries in appdata/roaming but it still won't go any further a notice appearing saying "Hmm there's a problem....".

No techie at all but could the installer be at fault ?

 

Random thoughts: Try each of these until successful.

Are you downloading from Mozilla or a 3rd party ? Do you use CCleaner ?



- Run RevoUninstaller Type Firefox in the search box for remnants. https://www.revouninstaller.com/revo..._download.html

- System Restore (point before Firefox installed) System Restore Windows 10

- Run sfc/scannow for corrupt files http://https://www.tenforums.com/tut...dows-10-a.html

- Try Mozilla Support https://support.mozilla.org/en-US/kb...munity-support

 

First tried Mozilla support as being the quickest to solve it which interestingly it turned out to be. They linked me to a world list of countries so downloaded UK and immediately it went straight through thankfully as I'd been getting nowhere.

All new to me, so I suppose I must have downloaded another country's link as there's always several available on the Net....
