Hello, On my system (windows 10, latest updates installed) the Firefox browser does not start anymore. I uninstalled it and reinstalled the current version without any change. I even can’t access the secure mode as after pushing the button to start it a Firefox-message will only appear for a tenth of a second before disappearing again - I have no chance to read it.

I checked several Mozilla support pages without finding any solution. The other browser (Brave) is running absolutely fine without any problems.

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}
