MuteTabsMatchingPattern — RheingoldRiver

Lets a user specify a pattern to match all currently-open tab titles against, and then mutes all tabs matching that pattern on button click or hotkey press (Ctrl+Shift+O).

Example patterns you might use (the asterisks are part of the pattern):
*YouTube*
*Twitch

If you want this to be a system-global hotkey (Windows), you can use it in conjunction with this AutoHotKey script:


SetTitleMatchMode 2
^!+x::
IfWinActive ahk_class MozillaWindowClass
{
Send, ^+O
return
}
IfWinNotExist ahk_class MozillaWindowClass
return
ControlSend,ahk_parent, ^+O
return
