I’ve started work on Kiwi , an open source (will be Apache license, I think) set of browser extensions (including Safari, Firefox, Chrome, Opera, and Firefox for Android(!)), which will serve internet communities (like HN and Reddit)! They should be done in a few weeks (the Chrome extension is mostly working). To my developer friends: get ready to fork! :D
I’m really excited by the Firefox for iOS project — sign up for their newsletter here (https://www.mozilla.org/en-US/newsletter/ios/). I plan to release Kiwi for FF iOS as soon as it debuts.
