when clicking on a link in TB email FF opens a new window instead of new tab
Hi! After the last couple of updates to FireFox, whenever I click on a link in my email (Thunderbird), FireFox opens a new window instead of a new Tab. In my FireFox preferences, I have it set to open in Tabs not Windows. It's really annoying to have another window popping up.
Any help will be greatly appreciated! I'm using FireFox 75 and Thunderfird 68.7. Using iMac with macOS Catalina 10.15.4. 1TB SSD and 40GB of Ram.
