I am wondering is there a way to make Opera 12 for Linux use say Firefox 27.0.1 user agent string perm? I cant find a way to set that up. Reason I ask is theres alot of pages that Opera has fits with. Twitter sometimes, Hotmail.com, gmail if you switch it to IE it just says something about install activex controls. ( that was an accident on gmail ) but twitter and hotmail sometimes have issues rendering.

hotmail = I cant click on anything at the top... OPEN JUNK ARCHIVE OTHER OPTIONS when you click on a message. If I switch to view as IE works fine.

Thanks,
Christopher
