I've just a little while ago installed a Mozilla Firefox add-on for downloading videos from the Dailymotion.Com, but inadvertently I've ended up clicking the "Download" button for a single video twice, resulting in starting two downloads of the identical video. I've tried right-clicking and then clicking "Pause" in the "Library" from Tools --> Downloads, but to no avail.
What should I do?
This is the link where I've downloaded the add-on:
