Checked the demo sites with Safari -> Flawless.
I became suspicious.
Downloaded and installed the extension.
Built a form in 5 minutes - used it with Safari and surprise - surprise no bugs!
Checked with Chrome (webkit too) -> no bugs!
Shame on you writing this review!
Though that I created a form in 5 minutes is worth givin’ 5 stars.
Don’t know the intention of this review but it encourages people like me telling the truth.
