Makes Tabs flash and Fries Facebook
Facebook was not working in Firefox. Obviously I suspected an addon but I did not suspect ColorfulTabs, but I thought I would check the reviews just to see. I started reading the reviews and I realized, thanks to previous reviewers, that ColorfulTabs causes Firefox to flash between tabs at random like this
So I turned ColourfulTabs off. I now also realise that it was ColorfulTabs that was preventing Firefox from displaying Facebook! I don't like the way that the default Firefox tab display is white on black but other than that ColorfulTabs did nothing for me anyone (it only colors the active tab and turns the others black on grey). Goodbye ColorfulTabs!
