for some reasen my laptop started to connect to the internet via my univerisities proxy server. today, however, web sites didnt load at all, instead it said: cant connect to proxy server. so i changed the network/proxy settings by deselecting 'use a proxy server for your lan'. consequently i was able to acces most web sites, apart from search engines. if i try to do so, it always comes up with: bad request, invalid hostname. what can i do?

You can find the connection settings in Tools > Options > Advanced : Network : Connection

If you do not need to use a proxy to connect to internet then select "No Proxy" if the default "Use the system proxy settings" setting doesn't work.

See "Firefox connection settings":


Reload web page(s) and bypass the cache.

  • Press and hold Shift and left-click the Reload button.
  • Press "Ctrl + F5" or press "Ctrl + Shift + R" (Windows,Linux)
  • Press "Cmd + Shift + R" (MAC)
