How to Downgrade Firefox version

Mozilla Firefox is a free and open-source web browser developed by Mozilla Foundation and its subsidiary, Mozilla Corporation. Firefox is available for Windows, Mac OS, Linux, and BSD operating systems. Its sibling, Firefox for Android, is available for Android. Firefox has an updated version, just in case you are not comfortable with the updated version and you would love to get back to your previous version. I will show you how to downgrade Firefox version.

Mozilla support center states that Mozilla announced a project known as Quantum in 2016, which sought to improve Firefox’s Gecko engine and other components in order to improve Firefox’s performance, modernize its architecture, and transition the browser to a multi-purpose model. These improvements came in the wake of decreasing market share to Google Chrome, as well as concerns that its performance was lapsing in comparison. Despite its improvements, these changes required existing add-on for Firefox to be made incompatible with newer versions, in favor of a new extension system -that is designed to be similar to Chrome and other recent browsers. Firefox 57, which was released in November 2017, was the first version to contain enhancements from Quantum and has thus been named Firefox quantum. A Mozilla executive stated that Quantum was the “biggest update” to the browser since version 1.0.
