I've moved from Opera & Firefox to Chrome just last Friday, and I'm loving it! I got the beta version, and it supports extensions. First thing I got was the exif viewer, which shows configurable information on mouse-over. Second thing I got was the ad blocker, which I've not tried yet as I only got it last night. Installation was dead easy, no crashes, and
it's the fastest and sleekest browser I've tried so far! Oh, and it's got an extension that allows you to open a tab within Chrome in IE, for those pages that won't work with anything else.. which I thought was a brilliant idea! Not tried that one either yet as I've simply not come across a page that didn't work in Chrome.
As a Norwegian I feel guilty for leaving Opera, but when Chrome is so much faster I can't NOT switch!
