WINDOWS 7 BROWSER JAVASCRIPT MEGA BATTLE [2025]

It’s [been a while] since we talked about browser benchmarks in Windows 7 environment.
And I definitely feel that it is a right thing and time to make another shot.
In the modern WWW most of the people are interested in raw JavaScript performance, so we’ll check it out in blip comparison.
And close this question once and for all. So, without further ado let’s get started right away.

Methodology: there are two testbed configurations, ultra low-spec potato machine from 2013 and relatively high-end workstation.
All background activities and plugins were disabled. Averaged value of two passes is written down.
Benchmark values were rounded to be more good looking to an eye.

BENCHMARK CONCLUSIONS

Ok, some final notes. [Palemoon] was not able to run the benchmark at all. People value this software
for it’s privacy, but it is quite debatable question due to previous controversial changes made back by developers in the past.
However it is still way better than Firefox and even more so than Chrome in this aspect.

If you are after the performance only choose Chrome-based browsers. Supermium is the best one, alternative forks a bloated or lack features.

CatXP is a Chinese fork of Chrome, delivers outstanding performance, thanks to its clean design and strong optimization.
However, due to significant bloat and extensive telemetry dialing back to servers in China, it is not recommended for general use.

Hacked Firefox forks are something in between. Note how Firefox 115 ESR is showing it’s age by demonstrating the most lackluster results.
