Mozilla is working on a new mobile browser for Android. Firefox Preview, that is the current name of the browser to distinguish it from the soon-to-be-replaced Firefox for Android, was released to Google Play in mid-2019.
Popular browser extensions such as uBlock Origin, NoScript Security Suite, LastPass Password Manager, Enhancer for YouTube, or Firefox Multi-Account Containers are all recommended extensions. Whether all of these will be fully supported when Firefox Preview will be released as a final version remains to be seen.
Mozilla expects to introduce official support for extensions in Firefox Preview in the first half of 2020.
