In Chrome web browser I can easily install addons for a full equalizer for better audio on Youtube. I use these two (both are necessary because the equalizer only works on HTML5, it does not work with Flash). This addon for Chrome will toggle all Youtube videos to play in Flash or to play in HTML5. It will stay in whatever of the two toggles you set, until you reset it. YouTube™ toggle Flash and HTML Players https://chrome.google.com/webstore/detail/youtube-toggle-flash-and/dhifbcifkgoghiaceajlicclinkjanfi?utm_source=chrome-app-launcher-info-dialog And this is the Equalizer (only works with HTML5 on Youtube). AudioEQ https://chrome.google.com/webstore/detail/audio-eq/lfafdlnjaliaghpjdajmlcnnblkgcefh?utm_source=chrome-app-launcher-info-dialog ------------------- Just install both addons to Chrome and then you have an audio graphic equalizer for all Youtube videos. ------ My question is this: Is there a Youtube graphic equalizer that works with Firefox? thank you!
