I too use FF on mobile, with uBlock, and I love it too. I don't understand how people put up with a browser without adblocking, on the tiny mobile screen. It's insane.

> some apps disregard my default browser preference

And how about all the apps that use a built-in webview every time you click a link (Gmail, Hangouts, rif, etc. etc.) rather than even calling a full browser. At least they typically have an "open in browser" option but that gets tedious, and they sometimes have a setting (buried deep) to always do so.

For me, this behavior is controlled through the browser. Firefox calls it "Custom Tabs" on the General settings page. Firefox preview calls it "Open links in apps".

If that's on, you get the mini-browser in the app, otherwise links go immediately to the full browser. (Just tested with Gmail, YMMV)

Oh wow, I just changed my default browser (on Android) from Chrome to Firefox and, with no further effort, Gmail (etc.) opens links in Firefox instead of the mini-browser thing. I always imagined the mini-browser as a part of the app that loaded irrespective of the default browser, but no. Cool!

You are. But gently spread the word so you become less of an outlier. :-)
