Protected Browser.
Switching to Protected Browser... COULDN'T LOAD XPCOM.!! it stopped a month ago and yet to get an answer , from you guys. It seems no one want to answer or try to find the error issue. Uninstall firefox and reinstall!!! No by doing that you will lose all of your data thats attached to firefox anywhere from you bookmark to user names and so on, Thas not a good solution AT ALL!!

There is no need to worry about losing personal data when you reinstall Firefox.
Your personal data like bookmarks is stored in the Firefox profile folder, so you won't lose personal data when you reinstall or update Firefox, but make sure NOT to remove personal data when you uninstall Firefox as that will remove all Firefox profile folders and you lose your personal data.
You can download the full Firefox setup .exe (Windows 64-bit) from https://www.mozilla.org/firefox/all/#product-desktop-release
That doesn't work even when you try to imported directly from firefox which the ext is CSV which is no where to be found!
