downloadhelper extension stopped functioning. I need to uninstall it but the extension website says to contact Firefox for such help. Will reinstalling it delete and re-create or will I end up with a non-functioning old copy and a functioning new one?
I use a year-old Macintosh with OS 10.5.8. I tried to change the video output format of downloadhelper extension from FLV to a format playable by Macs and Windows computers. In trying that, downloadhelper disappeared from the upper margin of the open screen and is no longer accessible. I want to dis-install it and then reinstall it, but there is no procedure at either the downloadhelper website or the FireFox website to do so. I am afraid to reinstall without first removing the extension. How can I remove it? The downloadhelper site specifically says to ask Firefox how to do it and offers no help.

I solved my own problem. Uninstall download helper as follows: Go to Tools|Add-ons. Click on extensions and look for "DownloadHelper in the list. On the bottom you should click on the <Uninstall> button. You'll need to restart Firefox.
Then, go to the downloadhelper extension install website on the Firefox website and reinstall downloadhelper.
Did you install the latest alpha (4.9.5a2)?
