Browsers have become an everyday part of our lives. We use browsers every day to browse Facebook, tweet out on Twitter, listen to songs on YouTube, and even right now you are using a browser to read this webpage. Whether you use Chrome or Firefox, extensions make these applications much better and more useful. Today in this article we are going to show you the 20 best Mozilla Firefox add-ons, apps, and extensions in 2020.
Why Mozilla Firefox is a better alternative to chrome
Well, everybody uses Google Chrome but the question is whether they want to use Chrome or not? Days when chrome used to be just a browser are long gone.
Chrome is filled with so many functionalities which makes it heavy and more than just a browser and Chrome is famous for consuming a lot of RAM when you open multiple tabs which makes your computer overall slow.
This does not happen with Mozilla Firefox. Firefox and him up to less than 30% RAM compared to Chrome. When multiple tabs are open, Firefox performs better than Chrome, making heavy sites open faster.
Apart from less RAM consumption, Mozilla cares for your privacy. Since 2014, Mozilla has been openly promoting online privacy asking its users to care for their data and keep track of where it goes and to whom it goes. If you are someone who cares about your privacy, then Firefox is the better choice compared to Chrome.
Firefox looks better than Chrome. It has been more than a decade and no significant change happened in Chrome’s UI. If you have become bored of that same UI day after day, then Firefox is right what you need.
It is not just the new UI you are getting with Firefox. It also has the option to customize the browser’s UI using themes. So, try different themes if start getting bored with Firefox UI.
But the best thing I like about it is the Firefox Add ons. Chrome add ons are good as well. But Firefox is famous for its extensions. Using these unique Extensions with Firefox makes everything easier. Let us check out the 20 best Mozilla Firefox Add-ons, Apps & Extensions.
Features of Mozilla Firefox
Mozilla Firefox has all the features a browser need. Less RAM and energy consumption is not the only thing which Mozilla Firefox offers. These following features make Firefox an efficient and useful browser:
