Brave?
No reason you can’t try them all, I have all three. I use Chrome by default, Edge when my aggressive security settings stop something from working, and Firefox in the increasingly unlikely case that something just renders weird (usually legacy sites). I have Brave also, I was looking at migrating to it because Chrome is a memory hog, but then I installed more RAM and kinda forgot about it.
As Mols says, Chrome and Edge (and pretty much everything else apart from Firefox, Safari and all iPhone browsers) are the same engine (“Blink”) so are broadly interchangeable.
Assuming both your Chrome browsers are logged into a Google account then they should sync all your stuff (and remain synced). The others will offer an import but you’ll likely have to set up Chrome locally first to give them something to import from.
I want to be able to use the backspace button to return to last page.
Alt-⬅ is the keystroke now (and alt-➡ to go forwards again). Backspace was disabled years ago. There might be a chrome://flags
hack for it or something now, I don’t know.
