Personally I don't think it's a sponsored post. If the author of the post didn't recommend something to workaround the issue, readers (especially non-technical one) might think there's no solution to the problem. Ideally the author should have mentioned about Firefox as well but he/she might not have used browsers other than Chrome, IE/Edge.
