The thing is, it doesn’t/shouldn’t. It should only appear if there is a password field on the page and even then only if you do not have a vault entry for the web page. When a vault entry exists, autofill should instead displayed, like this:
That is what happens for me. Is your experience different?
If you have a website that you absolutely do not want to be stored in your vault and for it not to show the autofill popup, you can add it to the “blocked domains” at the very bottom of the autofill settings page.
it’s better now with the extension settings configd differently than default.
Right, I meant any website with a password field. I guess I hoped BW could decipher between a register page and login page cuz I’d never want to gen a pass on a login page. Anyway, I would provide more info if I really was having a unuiqe issue here, but ticking that settings makes this work good enough for me now. Thanks for everyone’s responses! 
All it needs is to save the auto generated login after registering on a site, saving manually is madness. (I know I am coming from a non-programmer perspective, I assume it’s easier said than done)
But it’s so close to working.
Why even auto generate a registration for me if the extension isn’t going to save it… seriously, why would BW create a non-human readable password for you and then be like … aight good luck with that… it gives me grey hairs every time.
