Roadrunner web mail crashes upon loading page

B Body freezes computer when trying to login to PM system. Only way I've found is power down and restart. I do not know if this is firefox problem or upgrade to Koala Ubunto (910) Seems more Firefox related---had problems with Ubuntu 9.04? using last version of Firefox "Cyrillic?" was it called? So always used Firefox 3.0 I believe.
