I'm sure a lot of people around here won't be able to hear you over the sound of how Firefox somehow doesn't feel quite right on their macs.
Yeah... I dont quite understand how Firefox does invest into integration with third-party password managers, but not the one built into MacOS. Arguably Safari usage is comparable to Firefox in terms of staving off a Chromium monoculture. Safari usage on iOS is actually far more important right now to ensurage some semblance of compatibility.
Also, Mozilla is working on its own cross-platform password manager/password sharing between devices. I'm not sure what the intended policy is wrt password sharing (there may be passwords that I only want to have on one device), but this should be more useful than the Keychain, which doesn't even let me move my passwords from one machine to the next one without arcane incantations.
