I use Firefox as my default web browser on my Apple computer. I have many bookmarks, links and school related material that I can no longer access because an error message says that it cannot connect to the Firefox server. Please help. I'm a teacher and I can not get to my student material. I can not conduct any searches or click any links.

. . . it cannot connect to the Firefox server

Is that the exact message?


Type about:preferences#advanced<Enter> in the address box.

Under Advanced, Select Network.

[56+] Type about:preferences#general<enter> in the address box. Look for Network. +++++++++++++++++++++ Look for Configure How Firefox Connects and press the Settings button. If you are using a proxy, make sure those settings are correct. If there is no proxy, first try No Proxy. If there is a problem, then try System Proxy.


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}
