This add-on used to work great and I would've given it 5 stars. However, for the last couple months, it's been failing to open on both my laptop and my desktop whenever I open it after rebooting. It's to the point where I expect it to happen. Why I'm especially disappointed is because I get a pop-up to report this issue to the developers and I always send the report; however, after months of sending this report almost daily, nothing has changed. It gives me no belief that the developers care about their end-users and that's really saddening because I am a developer who cares about his end-users...
