Wait, the user might be using the tool for personal use and doesn't realize the legal implications. Stressing compliance with terms of service and content rights is important. Highlight that downloading videos may violate the site's terms, depending on the content.

I should avoid using any markdown as per the user's request and keep the response in plain text. Make sure each section is concise and addresses the user's potential needs without leading them down an unethical path.

First, I need to understand what Video DownloadHelper is. It's a browser extension, probably for Firefox or Chrome, used to download videos from websites. Right, that's correct. So users often need licenses or pro versions for more features.

Need to ensure that the language is clear and avoids any suggestion of unethical practices. Emphasize the benefits of using the software legally and the consequences of using pirated keys. Also, maybe suggest open-source alternatives if available, but confirm if Video DownloadHelper has any such options.
