Firefox about to work a lot more like Chrome

Mozilla is beginning to make a series of changes to Firefox that'll make certain aspects of the browser operate a lot more like Chrome. The changes are broadly designed to make Firefox more secure and stable, but they also have the downside of making it less customizable and potentially more of a resource hog.
There are a few key changes that Mozilla is making to get there. The first is that it's changing how extensions (which Firefox calls "add-ons") connect to the browser. Mozilla is beginning to require that they use a new method that's very similar to what's used by Chrome and Opera. While that means Firefox extensions may need to be rebuilt, it'll mean that Chrome and Opera extensions should be able to add Firefox support with minimal changes. "Developers who already support Chrome extensions will benefit since they will have one codebase to support instead of two," Mozilla writes in a blog post.
