Toolbar icon ALWAYS incorrectly identifies the active tab

[lincmad]

Whenever I click on the icon in the toolbar, it shows as the "active tab" a tab that I have open in a different window. It never, ever shows the correct active tab, nor even another tab in the active window. I tried clicking on "unmute tab" anyway, but of course it didn't work. The only option that works is "unmute ALL tabs," which pretty well defeats the entire purpose of the plugin. In particular, I whitelisted the website that is actually in the active tab, but it remains muted unless I "unmute all."

Additional info: the tab identified as "active" seems to be consistently the frontmost tab of the NEXT-TO-front window.
