Firefox freezes ONLY when entering a search with Google, must close FF via task manager in order to restart it - Windows 7 64 bit. Was not like this always.


Sorry, cannot give further details. 4.0 runs smoothly with all websites I visit. Each time when entering a search term in Google I get all the results, but that's it - FF then freezes down completely.

I have the same problem with Firefox 13 and 14 beta with or without plugins and extensions enables. I went back to Firefox 12 and everything is fine.

This can happen if you or an extension have modified network.http prefs.

You can check the network.http.* prefs on the about:config page and reset all bold user set network.http prefs to the default value (network.http.proxy.keep-alive should be true) via the right-click context menu -> Reset.
