For two months now, I've had increasing latency with gmail: often 20+ seconds just to load my inbox or return to a previous screen.
I know Firebug can slow down gmail. I have Firebug 1.4.2. Despite choosing Firebug's "Disable all panels" and "Off for all web pages" menu commands, I still experience this latency.
Is there anything else I need to be doing?
I'll immediately switch to a different browser. No gmail latency there.
