While Firefox 43.0 won't be officially released until tomorrow, you can already find this exciting open-source web browser update available via their mirrors.

Most prominent for Firefox 43 is that it lands the GTK3 integration support! After a lot of work, the GTK3 support is shipping in its first released version with Firefox 43 to succeed the GTK2 support. Using GTK3 also helps with the native Wayland support. Correction: GTK3 gets disabled in the default binaries now until Firefox 45.

Firefox 43 also has improved API support for M4V video playback, WebRTC streaming to multiple monitors, many developer enhancements, and various fixes.

More details on the Firefox 43.0 changes can be found via the beta release notes. You can find Firefox 43 for Linux x86_64 here.
