Looks generic. The website is very low effort (typos and template text unrelated to your product). Overpriced. Lacking in features. I doubt the legitimacy of the testimony, and your website claims there are far more users than the web store does. Even your images have the extension's name poorly photoshopped in.

What makes your product better (or at the very least not worse) than other products? Why should people (or orgs) use this over the countless other tested extensions? Also, this is pretty niche which makes will make it even harder to succeed.

If you're going to release a product, please put the minimum effort in terms of presentation.
