What are Beta add-ons?
Beta add-ons are unreviewed versions which represent the latest work of an add-on author. While different authors have different standards for beta code quality, you should assume that these add-ons are less stable than the general add-on releases. Please note that when you install an add-on from the “Beta Version” section of an add-on’s listing, you will continue to receive updates for that add-on as they become available. Like the initial version you installed, all beta releases are unreviewed by Mozilla and may harm your computer.
