Firefox 69 / 70 Beta Against Chrome 76 On Ubuntu Linux
With the ARES-6 web browser performance there wasn't any measurable change between the Firefox releases tested while Google Chrome remained a great deal faster than Firefox on Linux for this benchmark.
For the aging Octane benchmark, Firefox 69 and 70 Beta actually regressed the performance slightly compared to Firefox 68. Google Chrome 76 meanwhile was about 11% faster than Firefox 68.
The WebXPRT benchmark is one of the few cases at least on the Linux desktop where Firefox beats out Google Chrome albeit by a small margin.
With the Basemark browser benchmark there is a small boost in performance from having WebRender enabled but that is still beat out sharply by Google Chrome.
