I was kinda curious about how difficult it is to write a Google Chrome app or extension, especially with all the hype over Chrome OS recently. I wrote a Firefox extension a couple months ago (here) and I also wanted to know how developing extensions for the two platforms compared.
Anyway, my first extension changes all the text on every webpage to Comic Sans MS. It’s not all that useful, but it was fun to play with. Click here to test it out. The code (linked here), as always, is on Github.
