A 64-bit version of Firefox starts on my Win7 x64 SP1, but can't open any site. What's wrong?

Actually any 64-bit version of other browser don't want to work as well -- I tried Opera, Google Chrome, etc. Everything is the same. The programm can launch, but can't connect to any web-site. So uncanny. At the same 32-bit versions are working just fine. Please, help.

If this affects all browsers, the problem is within the system.

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
