Block URL by Keyword από Dork Yface

This extension does exactly as the title says. It blocks (ie: redirects) the user off of websites with URLs containing "naughty" keywords. At the moment, the list of keywords cannot be modified without digging into the javascript files of the extension itself. Believe me, I tried :(

Although it can be used as a general purpose "safe-search", the purpose of this is to help those struggling with porn addiction by blocking certain urls entirely- and to prevent such addicts from finding alternative sources for their porn (such as porn games on Itch.io).
I do not claim the functionality is unique. Other extensions like "Block Site" are far more powerful and comprehensive. However, I found their syntax for blocking links to be, quite frankly, a right pain in the arse. MY method simply checks keywords against the url, and file paths, syntax, or formatting of these keywords is irrelevant.
