Switch to audible tab v0.0.9
This WebExtension allows the user to switch to the tab that is currently making sound.
If there are multiple audible tabs, the addon will cycle through them and then return to the initial tab (the latter can be opted off at the settings page).
If there are no audible tabs, the addon will do nothing. Tabs that are muted by the user are also considered audible (this can be changed at the settings page).
If there are audible tabs belonging to other windows, these windows will be switched too (this can be opted off as well).
It is also possible to control the order in which the tabs will be visited: available options are 'left-to-right' and 'right-to-left'. This will only make difference if there are more than two tabs in a cycle.
Alt+Shift+A is the hotkey that can be used instead of the toolbar button.
Refer to the guide if you want to change it (the default hotkey is known not to work on Mac).
