Try Yandex Browser [0]. I've tried practically every browser going for Android and it's the only one that supports both Extensions AND Text Reflow [which I think is indispensable when browsing the web on a small screen]

As an added bonus, there's also a desktop version available. So you can get all that nice syncing going on too. Just like with Chrome and Firefox.
