Firefox 120 To Firefox 141 Web Browser Benchmarks
Turning to some WebAssembly benchmarks, there was a nice improvement found in Firefox 140 for PSPPDFKit WASM and is maintained in the current Firefox 141 development state.
And with Firefox 141 Beta showing the lowest RAM usage overall of the Firefox releases tested.
The WASM collision detect benchmark was showing better, stable performance since Firefox 133 with no real changes since for that basic WebAssembly benchmark.
The WASM image convolution benchmark as another simpler WebAssembly test case showed the same performance since Firefox 130.
