Firefox 43 Now Officially Available, But GTK3 Gets Disabled

Mozilla Firefox 43.0 is now officially available, but the GTK3 tool-kit support isn't enabled by default in the official Linux binaries.

As a minor correction to yesterday's article about Firefox 43 with GTK3, the default Linux build is sticking to GTK2. GTK3 support was present during the Firefox 43.0 Beta, but they have decided to postpone this support by default until Firefox 45.

If you are compiling Firefox yourself, however, you can continue to manually enable the cairo-gtk3 platform by default as all of the GTK3 code remains part of mainline Firefox.

Per this Mozilla bug report, "Although the GTK3 port is ready to ship, the update experience will be poor for users without GTK3 installed. We don't know what proportion of users that would be. Reverting to GTK2 for 43 beta and maybe 44 beta also would give some time to sort out [bugs]."

The official Firefox 43.0 release notes are now available here and you can download this web browser update via Mozilla.org.
