Junk button
Just updated to 115.2.3 (64-bit) before the JUNK button used to switch between JUNK and NOT JUNK depending if the email was one or the other, now the button does junk only and doesnt change when a junk email is highlighted

It's a known problem but either forgotten or being ignored by developers. https://bugzilla.mozilla.org/show_bug.cgi?id=1831713
Use J key to mark as junk, Shift+J as not junk.
What used to be named the Junk column is now named Spam, which could lead to confusion between TB's Junk controls and a mail provider's Spam.
