Why don't you stick to one browser that works or you feel good with ?
I have used both firefox 4 and Crome and to be honest they just complicated to use -why can't they make browser simple rather complicate with all new features?.
I prefer Firefox version 3.5 since that version has no problem with real player plug-in if you upgrade to new browser you update plug-in for version firefox 3.6 onwards as it won't play old version 12. At least good thing with new chrome version (11) it allows it to run old one
