I switched back a few months ago on all of my devices and only go back when I need Chrome devtools, Firefox is absolutely back in its prime. Feels just as speedy as Chrome on desktop and mobile, and handles large numbers of tabs better.

Ironically, or maybe intentionally, Google services are the only thing degraded. Google even refuses to give you the regular home page. Thankfully you can just get an extension that fakes Chrome useragent on the offending pages, but it's the darkest pattern I've ever seen
