Firefox is about to work a lot more like Chrome http://www.theverge.com/2015/8/21/9186809/firefox-becoming-more-like-chrome-extension-changes
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.""Developers who already support Chrome extensions will benefit.""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.Mozilla is also beginning to require that all extensions go through a security check before they can be installed (currently, only extensions that are submitted to Mozilla's official add-ons gallery go through these checks). While there will be some way to get around this — mostly for developers — this means that every extension that the average person installs will have to pass through Mozilla. For the most part, that's going to be a good thing. "Extensions that change the homepage and search settings without user consent have become very common, just like extensions that inject advertisements into web pages or even inject malicious scripts into social media sites," Mozilla wrote earlier this year. There are obviously some huge security issues in letting extensions run through a web browser unchecked, and Mozilla is beginning to change that.imo I enjoy both but like Mozilla better!!
