Long story short: Just had a power outage. Mac cut off. Turned Mac back on. Started Firefox. EXTREMELY sluggish performance. Safari is much better but something still doesn't feel right. Tried reinstalling Firefox, no luck. Firefox freezes and won't close unless it is forced. Any ideas guys? Why would Firefox all of a sudden turn rotten just because of a little power outage? Mind you, I have no surge protection or anything at the moment but I have just ordered an APC 1000w UPS backup unit.
