Firefox extension

You're right, when we rebranded the naming of the extensions it was to ensure users understand that 1Password for your browser (formerly known as 1Password X) is the way forward as far as the browsing experience is concerned. While the classic extension is still supported, it's no longer receiving any development updates.

As Ana suggested, I would recommend keeping the new one and letting us know if you come across sites where it doesn't work as expected. Ideally, this version should handle autofilling on all the sites you visit. If not, then we'll want to investigate and make sure it gets on our development team's radar to fix.
