The previous version of firefox fixed a lot of stuff for me. I updated to the recent one and I am back to square one. All google services come up with an illegal certificate error that can be bypassed, as do many other web sites. This happened also in the version before lats and rendered firefox unusable. It is also very very slow with Microsoft Live / Hotmail online Email application and keeps reporting a looping script error. Firefox consumes enormous ammounts of cpu and memory in these cases and cases my computer to severly overheat. This is really back to the state before the previous version and is quite frustrating.
