I want to block my phone's access to a website, for productivity reasons. I find myself at work constantly opening a tab to a stupid "funny things on the internet" sites and scrolling through it when I should be paying attention or being productive. On my computer I activated a helpful chrome extension that denied access to specific sites and it works wonderfully, but I can find no such thing for my phone. All I can find is "explicit content" filters as well as an ad-block ap, "Block it!" that I was able to jerry-rig in to blocking the site, but it often caused other problems, like denying any internet access whatsoever.
So is there any other method to just block a single website? A friend mentioned doing something with IP addresses? I'm willing to try pretty much anything, and will root my phone if that is necessary (I've been looking for an excuse to do that anyways!)
