No, I do however think it's a flaw as a programmer to not keep an open mind and at least
consider error reports that come in from other users/setups/browsers. At the very least, to keep a good reputation it isn't recommended to shoot off answers that would/could be considered rude and/or arrogant.
Either way, from what I can tell your scripts are good so I'll just wish you good luck in your continued programming journey and maybe I'll recreate your script for my own browser some day if I ever find the time
