for those who have trouble with FF 22 Rated 4 out of 5 stars

I applied this trick and it worked brilliantly. Thanks to Eitan Caspi.

Do this (After you installed the latest version of the FDM application!):
1. In the addons page of FF - do a "revmoe" operation to the disabled FDM addon.
2. Close FF completely.
3. In the FDM application "options" page, go to the branch of "Downloads" and then "Monitoring" - and enable the "Firefox" check box and click OK.
4. Launch FF and go to the addons page, where you will see the new FDM addon enabled.
Ta-Da! ;)

Two thumbs up Rated 5 out of 5 stars

This is a very very useful addon. I have been using FDM for a while and haven't used the plugin. I recently tried and really like it, especially the function to download almost any online video. This addon makes a good program better. Downloading multiple files and online videos is a breeze with FDM and its addon. Thank you so much developers.
