From rc3.org, another example of the Firefox team working hard to turn Firefox 4.0 into a Chrome-alike.

I already run Chrome on my Ubuntu box and on my Mac. Really the only things that prevent me from using Chrome full-time are:

• web app I’m developing at work must look right in Firefox
• no extension support in Mac Chrome yet

The lack of extension support on Mac is a sticking point for me because I’m a Delicious Bookmarks user. There’s a Delicious Chrome extension that I’ve been using on Linux, works great.

Another point is that Mac Chrome doesn’t have a functional bookmark manager yet. I keep starring things, in the hope that some future version will let me see and manage everything I’ve bookmarked. =)
