Firefox 68 vs. Chrome 76 Linux Web Browser Performance Benchmarks

Working as I do on a decently fast machine I have to say performance differences between the two don't concern me much. Both are fine in practice.

On privacy & many other grounds I'd far rather use Firefox even if there were a minor performance penalty. Unfortunately I find it just too unreliable. It always ends up simply hanging on most sites, which is fixed by (yet again) blowing away my user profile & setting everything up. Sync makes that less troublesome than it might be, but it's too annoying as a regular interruption of my work day to continue with. Chrome it is, because it works, and Firefox doesn't, regrettably.

As mush as I would like to switch to Firefox these results are very real, while doing frontend development with Angular or React the gap in Javascript performances is quite visible on every reload.

Jetstream, and even octane, are not relevant for most users.

JavaScript performance is good enough and has been for quite some time. (Server side node is another story)

If a website is slow, it is mostly because the website is shipping too much crap at the wrong time.
