- Let me toggle this on and off by clicking its icon (hijacking the double click on every site I visit is both intrusive and annoying);

Don't get me wrong, I think you had a great idea with this extensions. You just needs to polish it up a little bit.
You say that the it "infuriates you" that Google demands payment for adding an extension to the Chrome web store - but it's only $5 FCOL . Their motivation is purportedly to stave abusive extensions, and it might actually work like that to some degree (as well as contributing minimally to their cashflow). But regardless, $5 for an otherwise free service that gives you a much farther reach than your current method - might be worth it.
Google's webstore does indeed remove extensions that exhibit bad behaviour, but they don't audit the extension source code along with all updates to my knowledge.
