Why does "Download this video" keep popping up when there isn't even a video on the page?

I just closed 3 tabs in a row and "Download this video" was on the screen even on the fourth tab until I moved the pointer down onto the page to close it manually, it went out before I got there. Sometimes I have to chase it until I can hit the "x", then it stays off for a while.

Sounds that you have an extension that isn't working properly.

Start Firefox in Diagnose Firefox issues using Troubleshoot Mode to check if one of the add-ons is causing the problem (switch to the DEFAULT theme: Tools > Add-ons > Appearance/Themes).

  • Don't make any changes on the Safe mode start window.

Default is the only thing there even in Safe Mode, no other 'Themes'. This [even displaying the "Download this video" box] never happened before installing 4.x.
