I love Chrome. It's so much more stable than Firefox these days. That said, I do often have both running at once. Chrome houses my email box and Gtalk and things like that so when Firefox crashes I'm not out of the loop. It's a nice system.
Two ponies by the names of GrendoPony and Julien12826 write to tell us of some pony Chrome themes they've cooked up. The entire set of the mane six's can be found here, and Julien would also like to let you guys know that he's working on a Scootaloo theme, which can also presumably be found at the same link when they're finished with it.
