About Firefox Beta
Firefox Beta is Mozilla's pre-release build of its Firefox browser, carried under the package name org.mozilla.firefox_beta. It sits in the communication category and gives users an early look at where the browser is headed before the standard release channel receives those changes.
What the beta channel means A beta build occupies an intermediate stage of development: work has progressed far enough to be distributed broadly, but it has not yet become the general release. Anyone installing it is taking part in an earlier step of the rollout rather than the finished one, which is the whole point of offering a separate channel.
Developer and category The application is published by Mozilla, the organisation behind Firefox, and it is classified under the communication category. Because the package name differs from the regular release, it is recognised as its own application and can sit alongside another browser on the same device while you compare behaviour.
Storage and installation footprint The file size is 258.0 MB, which is a substantial download, so make sure the device has generous free space before starting the install. Additional room is typically needed beyond the file itself once the application unpacks and stores its data. This listing does not state a required Android version.
Release details and identification The build listed here is the current beta edition, and its accompanying release date is 2026-10-07. The beta marker carried in the version string is what separates this build from a standard release, making it straightforward to tell which channel a given installation belongs to.

Frequently Asked Questions
Which developer publishes Firefox Beta?
Firefox Beta is published by Mozilla, the developer behind the Firefox browser. It is listed in the communication category, and its beta designation indicates that it is a pre-release build offered through a channel that runs ahead of the general edition.
How much storage space should I plan for?
The file size is 258.0 MB, so set aside at least that much free space before beginning the installation. Additional room is generally needed once the application unpacks and writes its own data, meaning the device should have comfortably more than the file size available.
Can this build be installed alongside another browser?
Yes, it can. Firefox Beta uses the package name org.mozilla.firefox_beta, which is distinct from the standard Firefox package. A different package name makes it a separate application, so both can be present at the same time for side-by-side comparison.
How do I know if my device is compatible?
This listing does not state a required Android version, so there is no specific device requirement quoted here to check against. Review the details shown with this build before installing, and confirm there is enough free space for the 258.0 MB file.
What date is associated with this build?
The release date recorded alongside this build is 2026-10-07. That date pairs with the current beta edition, so it is the reference point for confirming which release of the beta channel this listing describes.
