Firefox Preview mobile browser adds support for extensions.
Mozilla developers have added support for extensions in the codebase of the mobile browser Firefox Preview (Fenix), which is being developed to replace the Firefox edition for the Android platform. The new browser is based on the GeckoView engine and the set of Mozilla Android Components libraries. The ability to connect extensions based on the WebExtension API is available for testing in nightly builds of Firefox Preview. An 'Add-ons Manager' option has been added to the menu.
