Firefox 84.0 Opens Extra Window when Launched via Hyperlink on macOS

I'm on an iMac running Big Sur 11.4 and Firefox 84.0. When I click on an external hyperlink (say from an email), a new Firefox window opens to my home page even though there is already a Firefox window open. There is only one tab in the new Firefox window (not two like previously reported) - the home page. This does not happen when I switch to Safari. In preferences, I have "open links in tabs instead of new windows" checked. This just started a few months ago. Also, in the example email, when i hover over the hyperlink, a little downarrow box appears to the right of the link. When I click on the down arrow, a window opens with the proper link, but it's not a Firefox window. At the top of this new window, there is a box that says "open with Safari". When I click on it, it takes me to a new Firefox window with only the home page tab. ????

This is a known bug on Catalina when you open an external link when Firefox isn't running.

I'm curious why you use such an outdated Firefox 84.0 version and not the current 89.0 release ?

Thanks for the reply. I'm running Big Sur 11.4 on the iMac. When I try to update Firefox, I go through the process and then when I say "Restart Firefox", it restarts but is still on version 84 and asks me if I want to update to 89.
