Ask HN: How can I monetize the chrome extension I made?

I created a Chrome extension called Facebook GIF Button, it alows people to easily post GIF replies in comments inside Facebook.

Thanks to some luck it boomed pretty quickly reaching 10k users in about 4 days.

I'd like to hear some suggestions on how to monetize my extension (I'm going through really hard times in terms of money).

I want to do this in such a way I don't disrupt the experience my users know and love. I once accepted an offer from some ad injection company and I am still regretting it.

Please help me out! Cheers
