mkVolumePerTab mkultra توسط

mkVolumePerTab lets you control the volume of HTML audio and video independently for each Firefox tab.

Open the extension popup to adjust the current tab’s volume from 0% to 100%, mute or unmute media, and optionally save a volume preset for the current website.

The first release is designed primarily for controlling voice and video messages in WhatsApp Web, but it also works with standard HTML <audio> and <video> elements on other websites after you grant access to the current site.
