I've noticed this on two different Macs. They're both on Catalina (10.5.5) and with the newest version of Firefox (76.0.1). On both computers, Firefox is set as the default browser.
When I use the 1Password mini-window from the menubar to search for a website and click Go, it succeeds or fails depending on whether Firefox has a window open.
If Firefox is quit completely, 1Password will Go correctly.
If Firefox has a window open, Go will work.
If Firefox is running but does NOT have a window open, Go does nothing.
It does not seem to matter whether I have the 1Password or 1Password X extension.
A reboot does not fix it.
As I say, this happens on two different computers (mine and a client's) - same behavior.
Thanks for reading!
