9+ Best Mozilla Firefox Add-Ons in 2021 [Must Try]

We have listed out a few of the best Mozilla Firefox Add-ons to install and try on your computer browser. These will help in enhancing productivity and skills.

Mozilla Firefox is one of the most underrated browsers of all time. Although Google Chrome has been used extensively by a lot of people around the world, Firefox has surpassed Chrome in terms of a lot of features.

The privacy and accessibility that Firefox offers are far better than most browsers today. It has numerous features that are very helpful and one of them is the add-ons that Firefox has to offer.

Mozilla Firefox has an in-built feature known as browser add-ons that are similar to the browser extensions that Chrome and Edge have to offer. Add-ons help one access features that are not readily available on the browser. The add-ons help one do a lot of activities at once including sorting out passwords, clearing ads, or even proofreading the documents.

A week back, my mother approached me with the concern of blocking useless ads on her Mozilla Firefox. She had trouble concentrating while working. So, I taught her how to enable add-ons on her browser and use it efficiently. The adblocker available as an add-on is quite efficient.
