Bug Description

Official Firefox releases and other distributions packages are built with `--enable-rust-simd` to improve performance. Official build option: https://github.com/mozilla/gecko-dev/blob/13788edbabb04d004e4a1ceff41d4de68a8320a2/build/mozconfig.rust#L12

`--enable-rust-simd` enables runtime detection of CPU features such as SSE and AVX in Rust written components.

To check if Firefox is built with simd open `about:buildconfig` and look for `--enable-rust-simd`.
