I'm using opera, only problem I have is the forum software sticking extra spaces in front of newlines and the occasional youtube video that doesn't work when I hit a google server that forces html5 on me.
btw Hotlinking shouldn't be a problem for any website that has a webmaster worth his salt, it's trivial to generate an .htaccess file that blocks hotlinking for any other site not in an approved list of sites allowed to hotlink. I've run a fair share of forums, you can even get creative and show "another" image in place of the hotlinked image so they don't do that again (VERY Evil smily)
