clicking the button shows a completely different set of videos that has nothing to do with the reddit thread i'm in.

Please support Firefox's page actions, that way the button just appears in the address bar when the page I'm on has a video and gets out of the way otherwise. RES does this with their "Dis/enable CSS" button appearing in the address bar when on a supported page.

Some uses prefer the standard placement, but I think this would be preferred by many.
