Chrome Motors To Extensions
The dev (unstable) build of Chrome for Mac now has extension support - I'm guessing that I'll be able to shelve Safari and Firefox on a more permanent basis soon. Not quite yet though:
The dev channel edition of Chrome lives up to its label; according to Laforge, the Mac preview crashes when the user adds a new bookmark folder if sync is enabled.
Chrome usage is going up, too - it's apparently up to 4.6% of all browser usage.
