Quite the irony then that people vote for LibreWolf, which is according to the same logic even more Firefox-ish (being a direct fork) than Chromium Chrome-ish (inverse relation). Not to mention Wolf looking half-dead, which sounds like a 0-day paradise. But whatever floats your boat, I just mentioned an alternative according to the OP’s query.

Thank you for the uninformed downvotes. Vivaldi is Chromium based with advanced adblocking and privacy features and other superior bells and whistles. OP wanted to avoid Chrome (for obvious reasons) while looking for a well-working multiplatform browser.

Vivaldi is a very mature product
