1Password classic extension autofills Firefox main window instead of private window

Hey @nekno ,

I'm trying to reproduce this here but things seem to work as expected. Here are my steps:

1. I open Firefox.
2. It opens on my homepage or on the last website I visited. I open a new private window and go to one of my websites or to google.com (if I stay on the empty private window open and fill cannot work at all).
3. I click on the 1Password extension icon on the top right corner of the browser, look for one of my websites and click on "Open & Fill".
4. 1Password opens a new tab in the private browsing window, takes me to the website and autofills the credentials.

Can you please check the extensions page in your Firefox and make sure there's only one 1Password extension in it? If there are two, disable/remove the one you are not using and see if the issue persists.
Also, when you open a new private window, make sure you're not trying to open and fill while in an empty tab.
