Having more than one version of a program may cause issues. You must remove the older programs. Then get the current full installer.

If the extension is not working, and no update is available, you might not have any choice but to disable it. You can do that on the Add-ons page. Either:

  • Ctrl+Shift+a
  • "3-bar" menu button (or Tools menu) > Add-ons

In the left column, click Extensions. Then you should be able to find Flash Video Downloader on the right side.
