Ghostery supports Firefox for Android [1]. For µBlock, there are two tickets open on GitHub [2,3] about Firefox for Android support.
Unfortunately, Chrome for Android doesn't support extensions [4]. But if you have a rooted device, you can block ads/trackers/etc. across all apps via AdAway [5], which manages a custom HOSTS file for you.
Oh please, listen to my sentiments. I would LOVE to use that browser of yours, but its unexplainable to me how anyone could stand using a mobile browser without text reflow.
I know Google is not making things easier[1]. Before every app that used WebView had it. Now Opera is alone with this feature on Android. Implementing it would give you a nice competitive edge and make many users happy. Somehow Opera is able to to do it super elegantly with WebKit code.
Hey, I'm like millions of those lay users who do not have rooted mobile devices.
WRT Firefox, it does not play nicely with Google services, like Gmail. WRT, browsers...I have tried many of them under the sun and all of them have a consistent disadvantage over Google, that is, speed.
I've got many lay users friends who still look for an Ad blocker out of the box, for their mobile devices. I have hope from Ghostery and uBlock makers, fingers crossed.
