Since the upgrade to V 3.5.7 Firefox has been extremely difficult to use.  I have often received "Firefox (not responding)" messages and have to use Windows Task Manager to close it down.
If I am typing a message in Facebook, for example, my typing will far exceed the rate at which the characters appear on screen, sometimes taking up to 5 minutes for a brief paragraph to be displayed or jamming meaning that I have to shut it down and start again.
My partner has also installed the upgrade and is suffering the same problems and an extremely slow response time.  My computer is running Windows Vista and the other is Windows XP BUT we are both ewxperiencing the same difficulties.

Reproducible: Always

Steps to Reproduce:
1. It just happens constantly!!!
2.
3.
Actual Results:  
It just happens constantly!!!

Expected Results:  
Worked properly as it has done for years...

you mean upgrading from 3.5.6?

Comment 2

Yeah, it was an automatic Firefox upgrade.  I've now started using the test version of 3.6 and am not having any problems.

Technically this particular problem has NOT been resolved but I have changed to a different (newer) version of Firefox...
