A popular open-source web browser well-known for its add-ons
Pros & Cons:
Mozilla Firefox is developed by a global team of volunteers under the umbrella of the non-profit Mozilla Foundation. It is completely open-source and is very popular amongst open-source proponents particularly Linux distro users. Firefox uses the Gecko engine which is also developed by Mozilla.
In 2011 Mozilla started a program called Rapid Build which intended to release new versions of Firefox every 6 weeks. This was in the main, a response to Chrome's rapid growth in market share and a perceived need to match Chrome's frequent new releases. The move had many critics and it has some significant downsides but it did meet Chrome's challenge. Although it has not been enough to prevent some decline in market share.
Firefox has had several defining features which are generally adopted by other browsers too: being able to pin a tab using the Pinned Tab feature to permanently keep a tab open on the tab bar for e-mail, Facebook, Twitter and other sites; Switch-to-Tab attempts to let you know when you already have a website open on a tab - as you type in the Omnibar (address bar) Firefox will check to see if you have that site open; the restore tab feature allows you to reopen tabs that you accidentally close or unexpectedly need after you have closed them. Firefox is also well-known for its add-ons which allow it to be customized with additional features provided by third-party developers. This is one of the main reasons for its popularity, but again Chrome and other browsers have large libraries of add-ons and extensions too.
Firefox does not have its own search engine unlike Internet Explorer and Chrome which default to their own search engines, Bing and Google Search. Instead Firefox provides a mechanism for users to choose their search engine on the fly. Not only can you choose from the big three search engines, you can also search Amazon, Twitter, eBay and Wikipedia. Additional search engines are available as add-ons. This feature is so useful that it is now widely used by other browsers.
Personally, I use Firefox browsers like Pale Moon and Waterfox more than any others although I hardly install any add-ons except internet safety checks. I generally have a lot of tabs open permanently on systems without a lot of memory so I appreciate Firefox's smaller footprint on my system.
