First and foremost: Do not save passwords in browsers.
Seriously, they all suck at it. I work in cybersecurity. Every time we see a workstation get compromised, one of the first actions the attacker's scripts do is pull credentials from the browser. We had one just a couple weeks ago and the users had dozens of personal passwords compromised this way. Please, just don't store passwords in your browser.
As another poster mentioned, BitWarden is great. I personally use KeePass. At least with Firefox, the Kee extension can let it autofill forms. I think BitWarden has something similar.
