Hey, this is somewhat of a cross-platform topic, so I'm not too sure whether or not it should be placed in this sub-forum.
Can you block access to all other websites besides en.Wikipedia.org on either Safari on iOS, Chrome on Android, Firefox on Windows or Chrome on Windows? I find Wikipedia to be the best website overall and the only one I'd like to visit and since I have only 200MB worth of data per month, I don't want to exhaust it on other more media-rich websites. I only want to know whether or not you can block access to every single website on the Internet apart from en.wikipedia.org on any of the 4 most popular platforms/browsers, or if it's one of those things that the only way to manage is by hand (e.g. just simply not visiting other websites) ?
