Browser extension issue (Firefox 75.0)

I've had a problem since installing 1Password 7: When using the browser extension (Firefox 75.0) I often find that 1Password doesn't select the correct login tab when I open it. For example, if I'm on a Google login page and I open the 1P extension the 1P login tab that shows up is my Amazon login (being the alphabetically first tab in my favorites list). I have to start a search process within 1P; as soon as I type "G", 1P jumps to the correct page, and works fine thereafter. But I believe 1P should recognize the page I am on and automatically select the correct tab to show. It used to work that way in 1P v6, but I'm not finding it so in 1P 7. Is there some setting that needs adjustment?

1Password Version: 7.4.4
Extension Version: 4.7.5.90
OS Version: 10.15.4
