Can you help me repair my FireFox Browser? The shortcut did not launch the browser. It stated that the file had moved or was no longer working. It still appears in my App folder but the only option is to uninstall it. I have a great deal of short cut tabs and all my stored passwords. How do I repair this? If I re-download Firefox will it access all of my stored information and preferences?

Hello and I hope you are doing good,

Sadly for me it is absolutely not the case It has been a few days since I can't use Firefox at all. When I try to open it, it tells that there is a "side by side error" and that I should use sxstrace.exe. I did that and it tells me that It can't find mozglue, mozglue.MANIFEST, mozglue.DLL. I use Mozilla in French (it is my mother tongue), and it can't find them in French, English or in Neutral :

Thinking it was also linked to the Redistribuables Microsoft Visual C++, I just downloaded all of them again.

My version of Mozilla is 152.0.6.595 and I am on Windows 10.

Please I really need your help and don't want to lose any of my tabs, bookmarks and passwords as I was making very important research for my PHD studies.

Real thanks in advance for your help.
