I don’t think the site http://browsehappy.com is the best or most original idea in the world but it does once again highlight issues with IE and maybe why we should warn/advise the public about other IE. And empower there browsing experience with better browsers.
I for one never use IE unless I have to in work (Legacy systems, I hate them too). I mainly use Opera and Mozilla if there are issues with cookies. But I've installed Firefox on my linux box and may start using it more and more in replacement for Mozilla. Specially because I love Thunderbird and Mozilla calendar. Yet to try sunbird yet…
