While ARES-6 isn't very popular these days for modern browser benchmark needs, Firefox 139 and newer were showing the best results.

Firefox RAM usage under ARES-6 with Firefox 141 Beta is also an improvement.

Octane as another older benchmark was showing some minor improvements on Firefox 139 and newer.

Again, the RAM usage is an improvement with the upcoming Firefox 141 release on Linux.
