I recently paid someone to create a firefox addon that will just be a small mint icon(I hope it’s ok if I used the mint favicon) . when you visit a site with mint, that has open mode enabled, then the icon will be green. If the /mint/ dir cannot be found, or the string “open” can’t be found on the /mint/index.php page, then the icon will be 40% transparent, and red. It will be open source, and free, unless Shaun wants it.
I talked to the dev, and he said it will be ready by next week.
