Firefox 2.18.2 disappeared?

This is what 1Password sent to me in regards to 2.18.x on Firefox

My apologies for the frustration, the current 1Password extension version available in Firefox is 2.15.1, which is a few updates behind Chrome and Safari. One of our Developers, Nolan, has provided an explanation in a Reddit post regarding why that is the case. I'll quote him here for convenience:

We've been going back & forth with Mozilla on trying to get our extension approved for release. Mozilla has flagged one of our settings as not adhering to their policies under https://extensionworkshop.com/documentation/publish/add-on-policies/#data-disclosure-collection-and-management, so we've been going back and forth on trying to find the best solution to accommodate their specific requirements while maintaining our extension functionality.

Mozilla's approval process is a lot more manual than other browsers, so sometimes we get hung up in specifics for Firefox specifically that we don't have to deal with for Chrome or Safari, which is why we're able to update Chrome & Safari still while Firefox is lagging behind.

I'm actively working on this & we're hoping to get something for this shortly after holidays (Early 2024). Believe me, it's on our radar & is something I've been actively involved with fixing, so it is being worked on.
