Ad blocking
-----------

Instructions:

* Download/install the latest NetGuard version [from GitHub](https://github.com/M66B/NetGuard/releases)
* Enable the setting '*Filter traffic*' (always enabled on Android 5.0 or earlier)
* Enable the setting '*Block domain names*' (default enabled)
* Import or download [a hosts file](https://en.wikipedia.org/wiki/Hosts_(file)) using the appropriate option
* Disable browser compression (Chrome: three dot menu > Settings > Data Saver > Off)
* Wait 10 minutes to let the Android DNS cache time out
* Test if it works by opening [this page](http://www.netguard.me/test)
* Enjoy ad blocking, but don't forget to support application developers

Note that:

* applications, like the browser, may cache data, so you might need to clear caches
* the test page only works using the hosts file downloaded from [here](http://www.netguard.me/hosts) (the default)
* YouTube ads are not domain based and cannot be blocked
* **ad blocking is not available when NetGuard was installed from the Play store!**

Which hosts (domains) will be blocked depends on the hosts file being used.

NetGuard provides the [StevenBlack hosts file](https://github.com/StevenBlack/hosts) download with the following additions:

* reports.crashlytics.com
* settings.crashlytics.com
* e.crashlytics.com

See [here](https://github.com/M66B/NetGuard/issues/277) for alternative hosts files.

NetGuard does not concatenate hosts files, so you will have to use a source which does this for you or do it yourself.

You can check the number of hosts (domains) imported by pulling the NetGuard notification down using two fingers.
