A couple of other things I want to throw in here are that it’s nice to see two open source browsers leading the way in innovation among browsers. In my opinion, browser innovation isn’t at the level it should be. Also, with all the talk about Google Chrome, very few people have noted that it is built on much of the same open source code base as Firefox. Google also contributes tens of millions of dollars every year to Mozilla for development of Firefox.
The fact that these browsers share much of the same code base may also make it easier for the huge community of Firefox extension builders to reinvent their extensions for Chrome. In turn, as Mozilla and Google work on transforming their browsers to mobile versions, that could mean solid mobile browsers with useful extensions, instead of the terrible mobile browsers we have now. There are many reasons why users should expect cross-platform mobile implementations of Chrome, as discussed here. Mozilla is already out with the alpha of Fennec, its mobile version of Firefox, which we discussed here.
These two open source browsers are going to duke it out in ways similar to what I’ve described here, working from much of the same code base. That competition is good for us all.
