Right now, I'm on a "Plugin Halt."
I noticed my computer running dog slow a few days ago, and saw that Firefox would use over 330 megs with only 3/4 tabs open. I did a clean install, but it saved all my extensions. I'm trying to eliminate them one by one to see which extension is causing these problems.
(It's gotta be an extension, nothing else. The pages I'm viewing are normal pages, no flash, nothing extra. And this is after a few days without closing.)
But that being said: AdBlock, BugMeNot, Cookie Culler, Target Alert, Forecast Fox, SessionSaver, and Minimze to Tray; those are probably my favorites. I've eliminated these as any cause to the problem. (I think.)
