Re: Repair Mozilla Firefox Windows 10

Moreover, I am not able to use see any flash videos or website with Firefox(chrome works fine).. Honestly I tampered with plug-in settings in Firefox that this happened. But right now I can't do anything to overwrite the setting...
Delete .macromedia/ and .adobe in your home directory, these can contain "Flash Cookies" stored by the browser. The same is true, if applicable, for Silverlight (Moonlight) and other plugins, they can allow websites to store data on your computer.
Here's the thing. Firefox doesn't store any user data in itself. What it does instead is create what's known as a "user profile" -- a directory in your home directory -- and store all your data in there. And by data I mean everything -- add-ons, themes, browsing history, stored passwords, and on and on. (The actual location of your profiles in the filesystem varies by OS; on Ubuntu and other Linuxes, it's generally in .mozilla/firefox in your home directory.) Data in the user profile is completely separate from the Firefox application itself, so removing Firefox via apt-get or the like won't delete the profile data; when you reinstall Firefox later, it'll just look up your profile and reload it all, which can be frustrating if you don't realize what's going on.
When you first use Firefox, it silently creates a default profile for you, and uses that profile from that day onward. But you don't have to use that profile. Firefox supports multiple profiles, and you can switch back and forth between them at will. This means that to get Firefox back to the way it was the day you first installed it, you don't have to touch the Firefox binaries at all -- all you have to do is create a new, empty profile, and use it instead of your old, cluttered one. Restart Firefox and it'll be like you never ran it before.
Yours will probably only have one profile listed -- that's your current, default profile, with all your add-ons and other stuff. It'll have a name that starts with a string of random characters; that's because FF had to come up with a name for it when it automatically created the profile, so it just used a random string.
Now Firefox will restart, completely fresh and new as the first day you downloaded it. Problem solved. And if you ever need to retrieve something from your old profile, like your old bookmarks, say, all your old data is archived in your old profile, so you can safely retrieve it later.
Also remember to update or dist-update (this last one is my favorite), after you removed firefox or any other software. Some users recommend doing a simple update before removing or installing programs.
