Chrome allows users to mute tabs, simply by right-clicking them and hitting Mute Tab. What I'm wondering is if there's a way to detect when a user has muted the tab.
To clarify, I'm wondering if there's a way for a website to detect when I've muted their tab.
No, this is not possible in Google Chrome.
Such events can be recorded using low-level APIs expoosed by Chrome but it cannot be done via any of the Web APIs available.
I realize this is an old question, but for anyone who may stumble upon this question in the future, according to Mozilla, it is possible to detect if a tab is muted on most web browsers using javascript APIs, if you are able to use install a browser exxtension.
