Minor bug for you: If I change the badge icon for 1Password X (under 'Toolbar button appearance' in settings) from the default blue-coloured version to the monochrome version an then restart Firefox, it returns to the coloured version again.
I am using Firefox 82.0 (64-bit) (beta channel) for Mac OS X on version 10.15.7 with 1Password X 1.22.4.beta (build #20126).
1Password Version: 7.7.BETA-10
Extension Version: 1.22.4.beta (build #20126)
OS Version: OS X 0.15.7
