manage add-on versions
I want to know how to manage the add-on versions. DownloadHelper 4.9.24 is the last version that works with my chosen downloader.
Their latest version doesn't allow me to use it, so I either have to downgrade Firefox or find some way to manage this add-ons version compatibility. I've been happy with FF for a long time, its a shame I seem to be given a choice of downgrading FF or doing without their add-ons primary function.

Downgrading even more is a bad idea security wise as you seem to be using the older Firefox 33.0 when 37.0.1 is the current.
On a Extension page at addons.mozilla.org there is a version history section on bottom of the extension page. This is where the previous versions of the extension is listed.
