Free Downloader for Firefox, Sea Monkey, and Pale Moon

Update Dec 2018: CYS has been removed from the AMO site as legacy add-ons are no longer compatible with current versions of Firefox. CYS has not been abandoned. We are rewriting the code from scratch, for all three browsers. We will be back soon with a new and improved version. Continue to CYS website here.
