After Firefox update to Ver 50 / 50.1 it will not open any Web pages, sits there with no error message and dose nothing. Chrome, Edge and IE all work. If I refresh Firefox it will work correctly but at the next restart it dose nothing. After reading many help forums I have down load and run the Mozregession tool. this is the result of the last tested build.

Chosen solution

After many hours trying to get FireFox to work, I have finally had succeed. I uninstall FireFox, then deleted all left over files from “Programfiles/Mozilla firefox. Then reinstall firefox and waited to it update plugins.

Some problems occur when your Internet security program was set to trust the previous version of Firefox, but no longer recognizes your updated version as trusted. Now how to fix the problem: To allow Firefox to connect to the Internet again;

  • Make sure your Internet security software is up-to-date (i.e. you are running the latest version).
  • Remove Firefox from your program's list of trusted or recognized programs. For detailed instructions, see

Configure firewalls so that Firefox can access the Internet. {web link}

Thanks for your reply. both of the above items I have tried a number of times without success. Have also tried the following:- Rolling back to Ver 49. New clean install. Starting with addons disabled. Starting in safe mode. Disabling ivp 6.

The only way I can make it work is to refresh Firefox, but it fails at the next start.

Start your Computer in safe mode with networking. Then start Firefox. Try Safe websites. Is the problem still there?
