Firefox releases from version 120 through 141 Beta were benchmarked.
Performance and memory usage were measured on an AMD Ryzen 9 9950X with Ubuntu 25.04.
Firefox 120 was used as the baseline due to automation issues with older versions.
Firefox 125.0.1 was tested instead of 125.0 due to removed binaries.
The same test environment and straightforward methods were applied for each release.
