i updated firefox and now I can't access the net on any browser. Wireless router everything is connected and up and running. Just not the browsers. uninstalled it, reinstalled it (didn't work), unistalled it again and internet explorer won't work either (not at anypoint after intial update was run. read several peoples simalr problems with the "could not read chrome manifest file" issue and solutions to no avail. uninstall and system restore did not work either. What did it change on my system, and how can I change it back?

Do a clean (re-)install:

Download a fresh Firefox copy 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.
  • Do not remove personal data if you uninstall the current version.
  • 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.
  • It may not be necessary to create a new profile, so first try if it works with your current profile and if not then create a new profile.

Your bookmarks and other profile data are stored elsewhere in the Firefox Profile Folder and won't be affected by a reinstall, but make sure that you do not select to remove personal data if you uninstall Firefox.

Thanks!! A clean install worked the second time. It must have been deleting the program folder. Thanks again!!
