I was really hesitant to switch to Firefox. It took a long time for me to finally leave the Mozilla suite and accept that Firefox was the one going forward.

My washing machine uses Firefox as well

Ecosia is another option but it is also Chromium based

It gets even better when you add:

Tab Stash

And

Auto Tab Discard

Tab Stash lets me stash a big ridiculous research or shopping session I'd want to return to, under a nice collection label for later.

And Auto Tab Discard will essentially unload open tabs you haven't touched in a while, so they'll load from scratch when you "wake them up", but they're not hogging all your RAM. It's fantastic.
