I've been a Firefox man for years and currently am on 3.6.3. (Vista 32-bit) It has recently slowed to a crawl, especially loading the home page (about half a minute) and navigating certain sites, including this one.
Tried some of the recommended tweaks ( editing about:config, removing add-ons, browser history etc) but it's gradually wheezing to a halt.
Any ideas other than the obvious reverting to IE, Chrome or Opera ?????
