This extension monofies the currently playing video or audio source with a single click on the extension button. The StereoToMono extension is useful if you want to listen to the video or audio you are currently watching in mono. It combines the left speaker's content with the right speaker's and vice versa, so you effectively hear the same sound from both speakers. This can be helpful when the stereo image in the video is unbalanced, heavily leaning to the right or left, suffers from phase correlation issues, or you simply want to hear the entire audio using only one speaker. It works on both video and audio elements on pages that support this feature. The extension is activated by clicking the left mouse button on its icon. For a full sound reset after adjusting the volume with the extension, it is recommended to reload the page. You can set the sound in your browser permanently for the current browser session (until you quit Firefox) by using the preference setting located under the right-click menu. Please use this with caution, keeping in mind potential issues listed below. Known issues:

On some pages, it is not possible to adjust the stereo image of the played elements. This is due to how the specific page is designed.
On some pages, when clicking on the extension button, the browser may mute the sound. This is due to the security configuration of the specific page or the server it is hosted on and unfortunately cannot be detected from the extension's point of view.
This addon may interfere with other extensions that also alter the sound at the same time. Please keep this in mind.
