Fontanello is a browser extension for Google Chrome and Firefox that lets you display the basic typographic styles of a text by right-clicking it.
I used it a lot in Firefox, but atm it doesn't work in Orion (release and RC).
Tried both the Chrome and Firefox version.
They both give this message when you try to use it on a website (even after reloading the page)
Thanks for having a look at this.
