It seems that nearly every post about Chrome results in a multitude of comments like this one, about how extensions are key and Chrome is useless without them. Google realizes this and is working on bringing extensions to Chrome. Mozilla, on the other hand, isn't working on bringing process-per-tab to Firefox at all. It almost seems like willful ignorance. Firefox may be dead simply due to Mozilla not having any long term strategy vision about how to stay relevant. The issue isn't that Chrome doesn't have extensions now, but what is Mozilla doing now to plan for the future when they no longer have the extension advantage. So far it looks like nothing. Even Firefox's vaunted new JS engine in 3.5 isn't going to be turned on for extensions, only web content. Meanwhile not only does Chrome's extension code get the V8 love, they also run as a separate process, which means they won't impact performance of browsing as much as Firefox's extension framework does.
