It works fairly well, but I have to reload the tabs to activate it, each time that I am on Youtube.

Pretty good. But I have to disable-enable the equalizing then reload the page every time I need to use it. I would expect it to always be hooked when a page is loaded while equalizing is enabled. Might be some recent youtube update causing it though...

nice tool but has problem with activation, sometimes stays inactive and there is no obvious way to turn it on. Just simple button on/off would be more comfortable.
