We make an effort to at least support the current Firefox ESR release (which is part of the reason that version 60 is supported: it was the ESR version until this summer, when it became 68). And I'm sure we'll need to raise the minimum requirement periodically going forward as well, in order to be able to adopt other new technologies. We're not able to remain backward-compatible indefinitely because then we can't take advantage of improvements and new features in the extension frameworks and browser itself to make 1Password better. I think the key here is that they're telling you upfront that it's not going to work because the browser is out of date and therefore incompatible. So 1Password X doesn't work there on Windows or macOS.

Okay, so, to get us on the same page here, when I manually copy the link to force it to install the extension, then try to sign into it, yes, I'm seeing the same thing you reported above: it isn't able to complete.

Anyway, you should be able to right-click where it says "add to firefox" and open the link in a new tab.Īha.
