* Title is too short (minimum is 4 characters)
* Body is too short (minimum is 5 characters)

Simply clicked the install button and refreshed my google calendar tab in Chrome browser and the favicon changed to today's date. Very cool!

I don't get why Google didn't do this already. It's pretty intuitive and desktop applications such as iCal do a similar icon preview.

The reason why I gave this script 4 stars is because it doesn't work on HTTP at the time of this writing. If the author of this script is reading this, you can just fix it by adding another @include line with the same thing but an HTTP prefix instead of an HTTPS

Google行事曆分頁上的圖標，本來醜醜呆呆的，一年12個月永遠保持第31日的藍底白字，但一年不過7個月是31天，實在不怎麼討喜，所以這個腳本可以讓圖標隨著日期的更動，顯示當日的日期^^

This script caused me to have to shut down my computer twice, even after I disabled the script. With this script running, if you click on a mailto: to open an email window it causes multiple tabs to open and the only way to shut it off is to disable the script and force close the firefox browser. then when you re-open, you have to close 100 tabs. Super annoying and I hope it didnt do any permanent damage.
