 Many thanks to
 [@Tread](https://www.phpbb.com/community/memberlist.php?mode=viewprofile&u=1973496) and [@cabot](https://www.phpbb.com/community/memberlist.php?mode=viewprofile&u=1337922) for gently 'persuading' me to publish this code as a phpBB3.3 extension, by pointing me to all the appropriate bits and pieces of code to be 'assembled' into an extension. Yay!
 
+Kudos to [@gvp9000](https://www.phpbb.com/community/memberlist.php?mode=viewprofile&u=2227069) for finding & fixing an obscure bug that affects Firefox.
