Firefox is able to open normally, however no site is able to load, the entire screen below the search bar appears blank. It appears that sites never begin loading. This also applies to the firefox settings and any pdf. I have tried both regular and nightly. It is likely I accidentally removed some important file within windows, but using a system restore did not help. I have also tried opening with safe mode with no success.

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
