Firefox, Mozilla, Thunderbird

With Firefox 148 hitting the stable channel across all supported platforms, Mozilla has promoted the next major version of its open-source, free, and cross-platform web browser, Firefox 149, to the beta channel for public testing.

Firefox 149 looks like a minor update that only introduces the long-anticipated native Split View feature, allowing users to view two web pages side-by-side in one tab. The Split View feature can be enabled by right-clicking on a tab, and you can also add a split view to a new group.

The Split View feature has been in testing in Firefox Nightly until now, and we can only hope it will land in the final Firefox 149 release since it’s a welcome addition for increased productivity. Split View can be enabled in Firefox 147 and Firefox 148 from about:config by setting the browser.tabs.splitView.enabled option to true.
