  1. I really wanted this add-on to work, and I'm hoping it can be fixed. That's why I'm reporting - if I didn't care about the thing it attempts to do, I wouldn't even submit this.

    At any rate, I have two issues to report:

    1. It does not work within Reader View, which I often use
    2. I was listening to a podcast just now, tried Speaker Booster, and it had no effect. Next I tried 600% Sound Volume, thinking perhaps that would work. Nothing happened. Then I just attempted to resume the podcast and got an error message to the effect of "this file type is not supported." Refreshed the page and my podcast was OK again. Re-ran the test and got the same result.

    This is not a critical issue, but much of the time, if I try using Speaker Booster after I've started playing content, it takes me back to the beginning rather than just increasing volume from that point.

    If these problems are just a matter of me making some app configuration problems, let me know what settings to try. If the problems are in the queue, try to alert us when the fix has been implemented.

  2. Addendum I submitted my bug request as a comment because the 'report bug' feature...um...didn't work. When I clicked [submit], the button didn't change color, there was no alert, nuttin'

  3. This does NOT do much, but there are other sound boosters that i have and they work

  4. Hiiiii, this does not work and one time i put on music with no sound booster, and it was quiet, I put on the sound booster and waited for it to work and nothing happened. I´m really sad :(

  5. Not a good app. Sound does not increase constantly, and seems to have reduced
