Big performance wins recently optimizing some core operations:
https://bugzilla.mozilla.org/show_bug.cgi?id=1994067 https://bugzilla.mozilla.org/show_bug.cgi?id=1995626
which brings it near chrome performance without the new v8 optimizations.
Still more work to do, including avoiding extra copies just like v8, and exploring more simd etc. Generic slow items for toBase64 and fromBase64: https://bugzilla.mozilla.org/show_bug.cgi?id=2003299 https://bugzilla.mozilla.org/show_bug.cgi?id=2003305
extra copying of results: https://bugzilla.mozilla.org/show_bug.cgi?id=2003461 https://bugzilla.mozilla.org/show_bug.cgi?id=1996197
No reason all browsers would not be able to be similar in performance eventually. Pleased this was noticed and being worked on by both v8 and Firefox team
Incredible that FF is even slower than a JS only implementation running in FF.
