Firefox has Disabled VDH

[Dirt]

Video DownloadHelper 5.5.0a5 has been disabled by Firefox because it can't be verified for use in Firefox.  Can you address this so we can still us the extension?

Here's the message on Firefox:

What can I do if Firefox disables an installed, unsigned add-on?

If an installed add-on is disabled because it hasn't been signed, contact the add-on developer or vendor to see if they can offer an updated and signed version of that add-on. You can also ask them to get their add-on signed. Another option is to visit addons.mozilla.org to see if there's a signed version of the add-on you can install.

Temporary fix - force Firefox to be using unsigned addons/extensions again:

- Open about:config

- Look for the "xpinstall.signatures.required" entry and change the value from true to false

- Restart the browser.

Thanks TearTwo.

You should also be able to use the latest beta (currently 5.5.0a11) that is installed on Mozilla servers: https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/versions/
