any upgrade more 3.6.28 stops during download to checking addons can not get any version to install

Using Vista premium. All upgrades beyond 3.6.28 to stop control addons and then he said: firefox does not. I'll get an icon, but it does not open. Have tried disabling firewall and the Norton internet security 2012. Deleted firefox prior to installation. I have no idea why these versions from 4 to 11 not install correctly.

Rather than delete the entire Firefox profile or test a new one that you can just delete or rename these files in your Firefox profile:

  1. Extensions.ini
  2. Extensions.cache
  3. Extensions. RDF

Make sure you have Firefox closed when you do this. Open Firefox after you deleted / their renamed and the problem should be solved.
