I found this link from another bug that was marked fixed in 96. It contains all bugs marked to be included in the changelog for 96: https://bugzilla.mozilla.org/buglist.cgi?f1=cf_tracking_fire...

From there I found this bug relating to cmd-clicking links in Gmail: https://bugzilla.mozilla.org/show_bug.cgi?id=1739929

You can find detailed discussion about what's going on there. I believe this is the ultimate fix: https://hg.mozilla.org/mozilla-central/rev/0fb0990124cf

It does not appear to be specific to Gmail, no.
