I can't log on to Firefox; I get a message "The update could not be installed. Please make sure there are no other copies of Firefox running on your computer, and then restart Firefox to try again."
There seemed to be 2 versions of Firefox on my computer, the second was Firefox Safe Mode which I don't even remember doing. Basically, I need to know if I need to uninstall and then reinstall. If I do that, will I loose my bookmarks and linked sites under those bookmarks?

Firefox Safe mode is a diagnostic mode that allows troubleshooting.
You start the same version, only some features are disable like add-ons (Tools > Add-ons > Extensions).
See http://kb.mozillazine.org/Software_Update (Software Update not working properly) Remove the files in the updates and updates\0 folder:
C:\Users\<user>\AppData\Local\Mozilla\Firefox\Mozilla Firefox\updates (%LOCALAPPDATA%\Mozilla\Firefox\Mozilla Firefox\updates)
C:\Users\<user>\AppData\Local\VirtualStore\Program Files\Mozilla Firefox\updates
- Download a fresh Firefox copy from http://www.mozilla.com/firefox/all.html and save the file to the desktop.
- Uninstall your current Firefox version and remove the Firefox program folder before installing that copy of the Firefox installer.
- Don't remove personal data when uninstalling.
- It is important to delete the Firefox program folder to remove all the files and make sure that there are no problems with files that were leftover after uninstalling.
