By now, you've probably installed the latest versions of Firefox and Thunderbird. The most recent releases include a lot of new and interesting features, but do they have all the functionality you're looking for? If not, that's where extensions come in. The Mozilla applications have too many extensions to try to write about them all, but I wanted to share some of the extensions that I find most useful for day-to-day browsing and email.
