Tu,

Humm.. maybe it is your system more so then firefox..
you should have a look at what else is running.. i.e virus software and all the other addons that get put in your startup process..
That Crtl Alt del in to Processes is a handy tool to see what may be causing some of your firefox problems..

Anyway.. heres a few tweaks for speed..

speed tweaks:
content.interrupt.parsing=true
content.max.tokenizing.time[integer]=3000000
content.maxtextrun[integer]=8191
content.notify.backoffcount[integer]=200
content.notify.interval[integer]=100000
content.notify.ontimer=true
content.notify.threshold[integer]=100000
content.switch.threshold[integer]=650000
network.dnsCacheEntries[integer]=256

As for now.. love Firefox, as the add-ons are just too good to go past..
