Better Volume Booster (formerly Volume Booster Without Dementia)

With an add-on such as Volume Booster Without Dementia it is possible to control the audio volume level of any media playing in a Firefox tab. With its help, users of the Firefox browser can easily adjust the volume level of audio playing in an opened tab. The promise this extension makes is that it can remember the volume level you set it to on a page.

Each page you visit in Firefox will have two separate sliders available, as provided by the Volume Booster Without Dementia add-on. Clicking on the newly added button, right next to the address bar, opens up a small popup window where you can easily adjust the so-called global slider and set the volume multiplier for the visited page using the per-domain slider.

While the global slider is permanent, the per-domain slider can be easily deleted using the “Recycle Bin” icon right next to it. Should you decide to do so, the global slider will be used.

Not only that you can increase the sound level, but this add-on offers you the possibility to lower the audio, if needed. In other words, the volume multiplier can be either positive or negative.

With Volume Booster Without Dementia, you can increase the audio volume of media playing in Firefox with up to 1000%, although it is surely not recommended you do so due to health-related issues. Moreover, please be advised that a significant increase in the volume can affect not only your hearing capacity, but also your headphones, if you are using any.

Also, please keep in mind that the extension might not work with audio content with a non-existent html tag.

Volume Booster Without Dementia can boost the audio level of media playing in any tab opened in Mozilla Firefox. Whether you want to listen to music louder or simply need to lower the loud volume of a playing clip, then this add-on is surely what you are looking for.
