Mozilla is working on a new Firefox version for Android, and the company recently released an update that allows users to enable extensions in the Nightly build of the browser. The first extension that can be activated in Firefox Preview on Android is also one of the most popular: uBlock Origin is available right now for anyone installing the early version of the Firefox.
Mozilla announced extension support for Firefox Preview back in October 2019, promising that selected add-ons from the Recommended Extensions program would be added to the new browser in early 2020.
