Personally, I humbly recommend you to use Google Chrome for faster browsing experience. Since DownloadHelper doesn't work with Chrome, also get a DownloadHelper for Chrome alternative or a DownloadHelper for Safari alternative.
Solution #1. Re-install DownloadHelper
By default, Firefox will update your addons automatically. But this might cause compatibility issues. If the addon works well, why update it? So if DownloadHelper doesn't work, re-install it to an older version might work. Get older version of DownloadHelper here: https://addons.mozilla.org/zh-CN/firefox/addon/video-downloadhelper/versions/.
Differently, if your Firefox version is too old, DownloadHelper might also not work. My suggestion is using the latest Firefox. Here comes the program. How to disable the auto-addon-update feature of Firefox? Actually, Firefox use Addon Manager to manage your addons. Open it by Firefox > Addons > Addon Manager and turn Automatic Updates off.
Solution #2. Make Sure DownloadHelper Not Working is True
Sometimes, you might find out DownloadHelper doesn't download MP4 video. I have to say, this is not the problem of DownloadHelper. If the video website doesn't provide MP4 video source, DownloadHelper naturally can't download video to MP4 format. DownloadHelper just downloads what's provided. In such case, you need a video downloader and converter like iTube HD Video Downloader.
Solution #3. Restart Firefox or Computer
No reason, just do it and DownloadHelper not working issues might be fixed automatically. Good luck!
Sometimes DownloadHelper Not Working issue comes up in new versions of Firefox, and when you try to download a video the window immediately closes and your file ends up never being downloaded. You might try to clear the cache and delete your cookies but this doesn't fix the DownloadHelper Not Working issue.
Solution: The easiest way to get rid of this on your Firefox browser is to reinstall Firefox. The root cause of this lies in the Firefox version that you have and if re-installation doesn't help remove the current version and replace it with an older version.
Another common DownloadHelper Not Working issue is when one is trying to download videos on YouTube. The download process shows but the data downloaded is "0 bytes" for any type of video.
Solution: To solve DownloadHelper Not Working issue when it comes to downloading YouTube videos, first try to close or reload the webpage. If this doesn't work fetch an older version from this link https://addons.mozilla.org/en-US/firefox/addon/video-downloadhelper/versions/ and reinstall it on your browser.
Downloadhelper is only officially available as a Firefox add-on but users have been able to port-it-over to other browsers so one might experience DownloadHelper Not Working issues on those browsers.
Solution: The solution for this is to just stick to using Firefox for downloads this way you wont get any issues.
Some video sites don't support Mp4 videos so trying to download videos that aren't in Mp4 format might bring up the problem.
Solution: This easiest work around for this is to find an alternative downloader that supports other video formats or just stick to sites that have MP4 support.
Sometimes when you try a video from the VEVO the download bar shows an empty file and the File size says "File not found".
Solution: A temporary fix for this is to visit http://www.youtube.com/html5 and click on "Use HTML5 Player when possible". Downloadhelper will then fetch other video versions offered by YouTube.
