Keyboard shortcut Autofill no longer works in Firefox or Chrome

I'm having this exact issue. I created a new post https://1password.community/discussion/136867/problem-with-ctrl-fill-on-firefox but wanted to comment on this thread that autofill with ctrl+\ does not work in Firefox 108.0.2 on Linux either with plugin 2.5.1. After pressing ctrl+\ you must then focus on one of the login fields with the mouse before the autofill populates the data. Used to work until a few weeks ago. I've confirmed settings are the same as pictured above.
