My desktop Firefox stopped connecting to wired network automatically and requires wireless connection to open pages. I have not changed any settings which led to this. I did try "No Proxy" setting to no avail. Any suggestions on how to get back to automatic wired network connection?

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
