Love it, but... Rated 4 out of 5 stars

I love the simplicity of this extension (basically an on/off switch), but it should be expanded to include a selectable list of proxies if you left-click on the (P). It doesn't have to be anything really fancy, just a selectable, configurable list. Otherwise, keep it as-is. Superb work.

This review is for a previous version of the add-on (2008.04.28).
