After installing video downloadhelper on Firefox, which was stated as successful, I have not seen the updated toolbar with the animated three balls logo and its arrow on my current Firefox toolbar, I have used downloadhelper in the past many times. but recently lost the animated three balls etc when trying to change my default search engine from yahoo to ask, and I suspect that my Firefox settings were altered inadvertently in error. Please advise what settings should be enabled/disabled to get video downloadhelper running again as it did in the past. Regards, James .
