What are some alternatives to Download Helper (for Firefox) on IE9 and Google Chrome?
the best you have to buy is Internet Download Manager the same is available as a trial for 30 days
Why would you want to use IE, firefox can get it done with fewer problems.
What I use myself is IDM (Internet Download Manager).. I could say it's great!
But I recommend you search for the lasted versions, since it has some issues with Google Chrome!
Here's a list of free download managers:
like Anay said, No addon for IE 9 or older, why not use Internet download manager, Orbit Download manager, or Free download manager.
there is no exact alternative to download helper for IE/Chrome,
but you try Orbit Download manager or Internet Download Manager it has similar extension for these browser to download video.
Or try software named "TubeMaster++"
no such add on in IE 9, but free download manager will work with almost all browsers that you may have.
