Excellent would be great if it stays at the same level for each website so that the volume neednot be adjusted for each tab

Straight forward, small and works like a charm.

I use this add-on more than any other.

works great ...very happy with it...no problems at all....recommend it ....

Very useful extension if you want an extra volume boost to your cheap weak speakers.
One little bug: the number on toolbar button doesn't update when I change tabs, so it looks like it's a different volume. It only updates when I click on it.

Does it's job well.

I don't know if it is really 600% I don't really have a way to measure but it 100% works. I have horrible hearing and hate headphones.

nice

excelent add on

I advise Firefox users not to install this poorly written extension.

The "details" section lists 4 feature bullet points and several quotes from positive user reviews. There are no instructions there, or anywhere. If the developer had spent 5 minutes browsing other extensions, he'd know that the details section is for instructions.

There is no settings page. Normally, an extension offers, if nothing else, alternative hotkeys in case, like me, a user is already using the extension's default hotkey.

Using this extension to switch to the tab with sound doesn't work if the tab is in a different Firefox window, making this feature more or less useless.

After trying the extension on several web sites that play sound, I find the extension is sometimes capable of increasing the volume but sometimes has no effect.
