Q: I bought a key, but it says "Not Verified." What do I do?
A: Check your firewall. The companion app needs to contact api.downloadhelper.net. Also, ensure your system clock is correct (SSL verification fails if the date is wrong). Finally, reinstall the companion app.
Q: Can I transfer my verified license to a new computer? A: Yes. Go to the old computer's extension settings and "Deactivate" the license. Then, install the extension on the new PC and enter the same key. It will now show "verified" on the new device.
Q: Are lifetime keys actually lifetime? A: According to the developers, yes. However, "lifetime" refers to the lifespan of the software version. If they release a radical new architecture (e.g., Video DownloadHelper 10.0), older lifetime keys sometimes require a small upgrade fee. Generally, though, they honor lifetime for major version cycles.
Q: Why can't I just copy the license file from a friend? A: Because the verification is hardware-locked and online. You would be copying an "activated" file to a machine with a different hardware ID. The server will reject the session and revoke your friend's key for suspicious activity.
Video DownloadHelper is one of the most popular Firefox and Chrome extensions for downloading videos. Historically, the extension was free. However, as browsers updated their security protocols and the developers required more resources to maintain the software, they introduced a paid licensing model.
When the extension detects a large video file or high-bandwidth usage, it may inject a QR code or a watermark into the video, accompanied by a prompt stating that a license is required for high-quality conversions. This has led many users to seek out license keys.
