The page https://adblockplus.org/android-about from the Adblock Plus website discusses Adblock Plus for android. It clearly refers to the version that runs in the background and blocks all ads (and is not in the Play store), not any of the browser versions for Android that are available in the Play store.
Clicking the link on that page for ''installation instructions'' takes you to https://adblockplus.org/en/android-install, which is an almost blank page displaying ''Want an ad blocker for your Android smartphone or tablet?'' and a button which redirects you to the android store (to install a broswer ad blocker).
I can't find any discussion of this online, and everyone seems to be able to download and install the correct version from the Adblock Plus website. Am I supposed to find it somewhere else? Why doesn't Adblock Plus provide it themselves?
