Suggestion: Show suggestions after unlocking

Just to check, what version of Firefox do you have?

I'm currently on 106.0.5

Do you run into this issue when unlocking the extension on any other websites?

Yes I believe so.

Before I go down the diagnostics rabbit hole can I confirm that when you did your testing you had the "Show autofill menu on field focus" option turned OFF?

Also for reference this is a video of what I see: https://files.wezm.net/simplescreenrecorder-2022-12-08_16.57.03.m4v

One difference from my experience to yours is I don't have biometric unlock, so the main 1Password window comes to the foreground so that I can enter the password. Probably shouldn't matter but perhaps it's worth double checking.
