I uninstalled Firefox and now am trying to reinstall and i get this error msg "couldn't load XPCOM.
I uninstalled Mozilla so I could use Internet explorer for a work project. I was unable to access the internet w/IE so I tried to reinstall Mozilla. When I click on the icon I get "couldn't load XPCOM. Some of the other suggestions were to copy the download on this second computer, save to flash drive and then add to pc. How do I download mozilla to a flash drive? Or how can I access the internet if I can't use Mozilla or IE?

Your bookmarks and other personal data are stored in the Firefox profile folder and won't be affected by an uninstall and (re)install, but make sure that "remove personal data" is NOT selected when you uninstall Firefox.
