Unfortunately, and I hate to "victim blame" (though you say you are not yet a victim), I think you have to take some responsibility and use a password manager with deliberation. IMHO the browsers all make this worse by giving you something that seems to work and your first notice that it doesn't anymore is when it stops, which is a terrible way for a security feature to work, but obviously they have incentives to lock you in, and boy oh boy is this one of the biggest ways that a browser can lock you in.

I think you should resist sooner rather than later and switch to something cross-browser and third-party.

But it's up to you, of course.
