I've been using the addon since it was released but after the latest update, I got this message:

"One of your browser settings prevents the “Alternate Player for Twitch.tv” extension from working. To fix it, open the tab with the address about:config. On the page, paste privacy.firstparty.isolate into the search field. The current status of this setting will appear below. Double-click it to change the value to “false”."

I know I can change this setting but I don't want to. I see no reason why this is now required to use the addon. Will it be fixed any time soon?
