Presumably works find enough. Tried to use it to access quora.com, and all I got was a captcha that I couldn't pass (which wasn't what I hoped for, but not totally unexpected either).

On restarting my browser however, this plugin caused ALL my tabs to reload (which is not great if there's hundreds of tabs open) which caused by Firefox to start thrashing the swap, and forced me to investigate how to remove a plugin when the browser is off. Soo, bit of a hassle. :(

Still, if you're not a tab hoarder like me, you'll probably do fine.
