Gmail, Google's popular Web mail application, is already full of useful features all on its own. But Firefox users can further customize Gmail with a variety of add-ons. Some only change the appearance, while others add functionality that makes Gmail more like a personal planner than just a plain old email application. Let's take a look at three Firefox add-ons for Gmail.
The first extension, GTDinbox, is a complicated collection of helpful and semi-helpful features. GTDinbox author Andy Mitchell claims his add-on is based on the action management method popularized by David Allen in his book Getting Things Done, which is based on the premise that writing down tasks frees a person to actually get those tasks done in a more efficient way. GTDinbox tries to help Gmail users become more efficient by grouping and labeling email communications as projects and task-oriented to-do lists.
