We all knew that Firefox 57 would stop using the old addons that we liked so much. Users can either revert to an earlier version of Firefox and use the old ant downloader OR move forward to the one Ant has introduced for Firefox 57. I have both versions of Firefox and can see why people prefer the old ant downloader, but hey at least there is a version for Firefox 57 that works on most sights. You are not being charged for using the program. If you can find a better downloader on the internet for Firefox 57 then use it and stop complaining. The new Ant downloader works in my opinion better than any other downloader extension on the internet for Firefox. Give some encouragement to the developers of the Ant downloader rather than throwing your toys out of the pram !
