not working for embedded (Spotify) content for which I just added this addon

I'm an older person and my hearing isn't what it used to be. This addon lets me turn up the volume on sites where I really need it. It has worked perfectly so far.

working nice

super

I was about to buy a speaker but this extension saved me

Download quick and painless; completion instantaneous; results exceeded my expectations.

very good

Nice sound though would prefer not to have to open the extension every time to adjust sound.

It would be much more convinient, if we could use address templates rather than individual web pages.

Thanks for this blessings of having pre-programmed gifts of software applications. I love it Universal Angels!
