When I recently updated FireFox, the DownloadHelper add-on was lost, and will now not download, though I have tried about 5 times??
When I recently updated to the newer version of FireFox, (version 3.6.13) the DownloadHelper add-on was lost, and it will now not re-install, though I have tried about 5 times?? When I clicked the icon to download the add-on the download progress bar indicated that the download was underway however, when it had completed, the add-on appeared not to have downloaded - including no icon - not even if I search for one. When I tried to download the same add-on again, the download window indicated the download in a faded color and it seemed to be indicating that I already had the add-on. Try as I might, I can't get it to work. DownloadHelper always worked with no trouble on the previous version of FireFox. Are you able to help? Many thanks for this service!

Delete the files extensions.* (extensions.rdf, extensions.cache, extensions.ini, extensions.sqlite) and compatibility.ini in the Firefox profile folder to reset the extensions registry. New files will be created when required.
See "Corrupt extension files": http://kb.mozillazine.org/Unable_to_install_themes_or_extensions
If you see disabled, not compatible, extensions in "Tools > Add-ons > Extensions" then click the "Find Updates" button (Firefox 4: click the Tools button at the left side of the Search Bar) to do a compatibility check.
You can also try "Reset all user preferences to Firefox defaults" on the Safe mode start window.
