I loaded up my Firefox 95 in macOS and did the command-clicking link, it opens it as new tab just fine. Not sure why this fix is needed for this new version? Perhaps edge cases that are reporting this issue?
I completely misunderstood the context. I realize it is about the Cmd
+Clicking as in trackpad clicking, not the Cmd+Left-Mouse-Button originally. My apologies about the confusion. I am surprised this bug exists and I never encounter that kind of bug since I always use the mouse for the clicking.
