Mozilla Firefox Version 57 Released with Security Updates

Recommended Posts

Mozilla sent Firefox Version 57.0 to the release channel today. The update includes four (4) security updates, 1 Critical, 1 High, 1 Moderate and 1 Low.

 

As of this posting, Firefox ESR remains at version 52.4.0. Update: Firefox ESR version 52.5 has been released.

 

With this release, "legacy" add-ons (XUL-based) will no longer function. This update changes the add-ons system to the WebExtensions API. The Mozilla Add-ons portal will list only WebExtensions-compatible add-ons by default. Legacy Extensions are listed separately located under Tools > Add-ons. From there click "Find a Replacement"and check the three pages of available extensions.

 

In addition, this update introduces the new Quantum engine (Firefox Quantum) which is replacing parts of parts of the familiar old Gecko engine.

whoa, just restarted after installing the update to FF57. It is MUCH faster, i need to check if my extensions are still loaded.

text has been better looking, photos - depends: if low resolution (less than 200) they look worse , higher resolution looks very good.

Odd thing I noticed when installing the stable version through the Ubuntu repos after using the beta version for a while, is that the Ubuntu modifications add-on is still installed as a dependency (or recommended package), even though it's a legacy extension and no longer gets loaded.

 

And yes... I love this browser again... This is a major improvement! :clap:

Firefox Quantum is awesome. I was pleasantly surprised when I got the update on Tuesday. I went around and starting updating every physical computer and virtual machine I had. :clap:
