No, actually it's as fast as Chrome is now,[0] and substantially faster than Chrome was two years ago.[1]

I just run it on my Windows PC and it is 1.5x times slower on JetStream vs Edge.

While Mozilla deserves some heat for abandoning official support of PWAs, for my use this add-on has filled the role just as well: https://github.com/filips123/PWAsForFirefox

Thanks for this. It is pretty surprising that this is one of the most requested Firefox features and they haven't done anything here; all the world is moving to web apps and Firefox is not helping.

Suspect that may vary based on host system and OS.

~455 on Chrome, ~452 on Firefox (fully patched windows 10, 7950X3D).

3 runs including a cold start for both, variance on FF was +/-9.6, Chrome was +/- 6.0.

I'd say they are there (on that specific benchmark).
