I am using Firefox 83.0 (64-bit) on Mac OS Big Sur 11.0.1. Until recently, when I would click on a hyperlink within a pinned tab, it would open in a new tab. (To be sure, this is *without* pressing the Control key on the Mac, or without right clicking on the mouse --> open link in new tab option). But now, hyperlinks inside pinned tabs open in the same window. This is a workflow nightmare because I am used to having links originating within my pinned Gmail window open in a new tab. I have followed the instructions at https://support.mozilla.org/en-US/questions/1283295, but this does not help.
