I'm just curious, I don't have any particular issues with this. I can see 1Password X in the Mozilla addons store for Firefox extensions, but I don't see the "normal" 1Password extension that communicates with the desktop app. The non-X extension needs to be installed directly from the website.
I assume there is a technical reason for this, since you've added 1Password X to the addons store. Can you share what those reasons are? Sorry if you've already answered this question, I wasn't able to find it in my searching.
Obviously I trust you guys, or I wouldn't be giving you all my passwords, so I don't have any trust issues. The only minor problem this causes is that I need to manually install it on all my computers instead of Firefox Sync doing that for me automatically. :-)
