Firefox has just updated itself to 22.0 and now I can't connect to any webpages. I've gone through all the suggestions on the help page and none of them work. Internet Explorer has not been working for several months and other programs, such as Windows Media Player, have not been able to connect to the Internet either but Firefox has been working until it updated today. I've checked my internet connection and am now using another computer on the same network.

I had this problem several months ago after Firefox updated itself and eventually tried restarting my computer but it failed to restart and I had to send it off to be repaired.
