I actually discovered this because my browser would not stop running at 100% cpu utilization about 3 days ago, not doing anything, just sitting at Google.com with one tab open. It freaked me out because I couldn't find any documentation on the extension. Once removed Firefox was running fine again. I guess I'm relieved to know it wasn't some malware or something more sketchy, but I am wondering what it was doing pegging my cpu at 100% whenever my browser was open...

Whatever you experienced is very unlikely to be caused by this add-on. The add-on only initializes if you manually dig into about:config and enable `extensions.pug.lookingglass`. Otherwise, it just starts up once at browser launch, checks that preference, and shuts itself down. (https://github.com/gregglind/addon-wr/blob/59659431fd2a75c33...)

If you're able to consistently reproduce the issue, please let me know.
