Following the [1]Firefox 148 release with the new AI controls , Mozilla promoted Firefox 149 to beta today.

Most notable for end-users with the Firefox 149 Beta is now having [2]the new split view mode option by default . Split view mode has been riding on by default in Firefox Nightly the past month and now it's in the Firefox 149 Beta 1 milestone.

Hopefully the split view mode continues working out well during the beta period and then Mozilla is able to keep the option available by default in next month's Firefox 149.0 official release.

The Firefox 149 Beta also brings better robustness of HTTP/3 upload performance on unstable network connections, a new Reporting API, and other enhancements.
