IT WORKS! :)) Loved it long ago, used the "HackTheWeb" update until it ceased working ... and never found a satisfactory alternative (so I used Seamonkey when I absolutely "needed" it). Now Aardvark Duex (!) nails it. So pleased!! And *thankyou*, @dvogel. :)

My favourite HTML removal/tweaking tool of all-time! I've been using it for years- probably since its inception. I'm shocked it's available again after sticking with Firefox 56 for so long, then having to upgrade to 84 on another laptop. Highly recommended!
