And Apple provides end to end encryption of browsing history so it can’t decrypt your browsing history

> What’s interesting about the Apple decision is that it appears to explicitly separate browsing history and bookmarks, rather than lumping them into a single take-it-or-leave-it package. Apple doesn’t claim to provide any end-to-end encryption guarantees whatsoever for bookmarks: presumably someone who resets your iCloud account password can get those. But your browsing history is protected in a way that even Apple won’t be able to access, in case the FBI show up with a subpoena.

And I slightly misspoke. I said it was only supported by Chrome. More accurately, it is supported by Chrome and some Chromium based browsers.
Many new versions and updates of FF that I've tried have claimed to be much smoother and more efficient, only for the exact same shit to start happening across the years and multiple laptops used.
I went back to Firefox about 5 years ago and not even once missed Chrome since.
The only time I've had to touch about:config in the last several years was due to some smartcard related bug caused by an external library, that forced me to tweak firefox's behaviour. Once that bug was resolved, I switched it back.
Firefox being slow is well into the self-perpetuating FUD territory.
