Updated to new version of Firefox. Download Helper now does not work, icon no long moves, will not download youtube videos, will not show anything in download queue, nothing. Tried to go back to version 4.86 - don't know how to do this.

Which version of Video DownloadHelper are you currently using (4.9.4)?

You can try to reset the dwhelper prefs on the about:config page to see if that helps.
You can open about: pages via the location bar like you open a website.


Version 4.8.6 can be found here: https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/versions/

Some recent changes at youtube made the various quality variants to be not detected. This version fixes the problem: http://www.downloadhelper.net/install-beta.php?version=4.9.5a2
