I’ve been using Firefox as my primary browser for several years now, having left Chrome back in 2011. There are reasons for this beyond functionality; for example, I love Firefox as an example of true open source software and for its emphasis on security and privacy. These are places where Chrome comes in “close but not quite” and, as always, Internet Explorer is way, way off the mark. But I’ve also come across a number of add-ons that have made my Firefox use more powerful and comfortable.
