It doesn't work. I use "push to kindle" on my desktop pc and it's superb but this is fully useless. I used the same e-mail and couldn't send any content to my Kindle.

I love this extension. It's the simplest way to send articles to my Kindle.

The main problem is that it needs some way to customise text size and the like; some site's such as Quanta send text too big.

@authors, I can watch around the source code and add this if you want.
