This product works really well, and when some site changes things up, it doesn't take the team very long to resolve the issues.All automatically. I've never had to wait more than a couple of days or so, to have the development team fix whatever went wrong on a site. Or on a Firefox Update.
It's a no-brainer. I will always have this software on my desktop. If you can afford to, you should support developers like this. A few bucks here and there will help.
