While the Video DownloadHelper extension works seamlessly with Windows, it may sometimes stop working completely.

But if you want to watch videos on a browser without buffering, we recommend some of the best browsers in this detailed guide.

In this post, we will highlight a few workarounds that may help you fix the Video DownloadHelper not working in the Firefox issue.

Why is DownloadHelper not working?

If your Firefox Video DownloadHelper add-on has stopped working out of nowhere, it could be due to:

• An outdated Firefox version
• Too much of Browser cookies, cache, and search history
• Unsupported formats of video and copy-protected
• No official update available for the new DownloadHelper version

The good thing is, that we have come up with a few possible ways to fix the issue when the Video DownloadHelper is not working in Firefox.

Quick Tip:

DownloadHelper may be working fine and the underlying issue is actually with your browser. Try installing it in Opera One instead. We suggest this browser because it’s very responsive.

Despite not having a dedicated DownloadHelper extension in its add-on shop, it supports all Chrome extensions. Just search for it in the Chrome web store and select Add to Opera One.
