Firefox and Chrome also have pretty solid built-in password managers. If at all possible, these built-in ones are preferable to any third-party password manager, at least from a security perspective. (Browser integration is *really* hard to do securely, and these avoid those pitfalls by already being part of the browser!)

I think a big reason people use external password managers is so that they can sync passwords between laptop and phone. Firefox and Chrome actually have a sync option built-in, though! (Warning: Chrome won't force you to set a master password before enabling sync, but it is *critical* to security. Always use a master password!)
