setup: winxp pro SP3, Firefox 3.0, ZA suite 8.0.059, Forcefield 1.1.79

I do quite of bit of medical searches via MedLine which can result in multiple tabs opening within one browser session as I link into my university to download articles. As well I often will do multiple browser windows (up to 4 not including tabs) searching MedLine as I do simultaneous searches on related medical topics. I installed Forcefield and I noticed that as I conduct the searches the firefox windows and tabs freeze up forcing me to close all the sessions or unload forcefield.

It happened sometimes before Forcefield but became 'common' with Forcefield. I don't know if it's b/c I have so many windows and tabs open OR that Forcefield goes wild when I have the browsers and tabs open.

FYI...I had to turn off ForceField in order to work without locking up too much.
