Known Issues
- If you see a shortcut that's set to the "Win" key it will not work, please disable it or set it to another binding
- Successive presses of the "Toggle Mute" command don't work. Switch to another tab then back before re-pressing toggling mute

The issues below are mainly Firefox issues:
- If the popup icon is hidden inside the overflow toolbar menu, the popup shortcut won't work.
- Input might not focus when the search popup is activated for certain users (Windows users mainly report this). Bugzilla Report. Fixed in FF60. Workaround for now is pressing tab after the popup opens (thanks recycler.fox for the suggestion)
- Popup activation shortcut: changing this is possible after FF60, still need to update the extension to support this
