Browser and browser extension test pages

Introduction

When investigating and debugging browser and browser extension bugs, it's often useful to first have a minimal test page that can be used to reproduce the problem. Over the years, I've created a bunch of these test pages, so I decided to give them a proper home. Bear with me while I try to find them all and migrate them here!

Feel free to use these test pages too, just not in your automated tests!
