Firefox is a web browser from the Mozilla project, which is a part of the non-profit organization Mozilla Foundation. It can be downloaded free of charge to install on any popular operating system including Linux. If you have installed minimal Debian 11 bullseye with GUI and want to install Firefox browser later then here are the commands.

Being an open-source project, this browser is constantly getting new updates from its lively community. There are numerous extensions available which we can use to increase the standard range of functions as required, contributing to the great popularity and spread of Mozilla Firefox.

Each version of Firefox goes through several stages of development. As an interested user, you can extensively test new features in the Nightly, Aurora, and Beta versions before the official release. Known security holes are fixed within a few hours, so you can surf the web safely.

Well, Firefox is available in two editions one is Firefox -ESR, and the other is Firefox Standard. 

The Firefox “Extended Support Release” (ESR for short), default in Linux systems, is primarily intended for companies that only want to update their browser at longer intervals. Hence, extended version support for businesses those doesn’t want to compromise on stability factors.

Whereas the conventional Firefox version (standard) is updated with new features every four weeks, the ESR version only appears with new features around once a year – but is still supplied with the latest security updates.
