Since Firefox is rich with standard features, many users are content with running the browser as is after installing it. Power users, however, know that they can tailor the browser to fit their individual browsing needs. They make Firefox do things that make browsing more productive, convenient and fun.
But how do they do it, you ask?
Power users take advantage of add-ons, or extensions. Add-ons allow you to customize your Firefox browser and give it extra functionalities you never thought possible. For instance, with the right extensions and add-ons you can colour code your tabs, capture and convert web pages, get a number of quick-access toolbars and buttons and more.
With a number of different add-ons, you can even make Firefox outperform standard browsers. Below is a handy guide to 150 great Firefox add-ons to get you started. Try them out today!
