HOLY CRAP!!!!..LOL.. I use safari on my mac,, love it and the top right it has google toolbar,, dont use,, cuz im pretty fast with "apple+T" or "cmd+T",, i use as much as possible shortcuts,,lol..dont like to install soo much clutter
I use the Imageshack Toolbar .. Since I use Imageshack for my Pictures its quite handy .. Not to mention the "screenshot" button that also is very handy
