I had similar problems with firefox 36 on Lubuntu (and Ubuntu). Firefox crashed on certain websites and when I clicked "x" to close the window, a message window appeared:
The window "Mozilla Firefox" does not seem to be responding. Do you want to force it to exit by sending the terminate signal?
It happens again when I login yahoo mail.

I did a bug report for this here:
https:/ /bugs.launchpad .net/ubuntu/ +source/ firefox/ +bug/1434848
The problem with firefox happened especially on certain sites as:
http:// www.agame. com/ www.linuxquesti ons.org/
http://
Now I try with SeaMonkey on these sites, and it crashes too.
