Hello,

I just downloaded a Youtube downloader add on to my Firefox browser, and when I click on the 3 horizontal bars in the upper left corner, and click on the add ons tab, I see the add on. But there is no icon for this add on in the upper left corner. And I am not able to use the add on. What do I need to do to fix this?

Thank you

Are you possibly using Private Browsing mode and is the extension not enabled in PB mode ?

Hello cor-el,

Thank you for the response. I change the private browser setting for this add on, but still do not see an icon, or any way to use the add on.

Thank you

Did you look in the overflow area (>>) on the Navigation Toolbar or check customize mode ?

Some of these download extensions add a button to the YouTube page to download the video from this web page, so maybe look for that.
