This add on does not work. It's HIGHLY disappointing. The one that does seem to work isn't compatible with the latest Firefox. Even more disappointing. In fact most of the add ons I used are now incompatible. AND THAT IS REALLY PISSING ME OFF, because now I'm left trying to find alternatives. And because things like this don't work, it makes it take longer. I had to manually resume my download which is failing multiple times before it completes, but can resume (manually). Time to go back to the drawing board I'm afraid Maurice.
