Benchmarking Mozilla's Firefox Performance Over The Past Two Years

StyleBench has been improving with time for this CSS style benchmark with the highest performance seen out of Firefox 70 but with a slight pullback on Firefox 71 and later.

The Maze Solver web test has improved with time and since Firefox 67 has been delivering stable performance at its best.

The Speedometer JavaScript benchmark has been improving in recent Firefox releases where Firefox 71 isn't far off its highs from Firefox 69.

The PSPDFKit WASM (WebAssembly) benchmark has improved nicely since Firefox 60 which is great to see considering the growing popularity of WebAssembly.

If taking the geometric mean of all these Firefox web browser tests carried out, the performance is largely flat from Firefox 57 to Firefox 71 stable with just a 6% improvement between those releases that are two years apart. While overall there is a few percent gain, as shown in some of the benchmarks have been pullbacks in performance for Mozilla Firefox on Linux that hopefully we'll see addressed in 2020 with continued optimizations by Mozilla developers.
