Frequent updates force a pop-up on you when you try to use the extension -- it shifts focus to a new web page it opened. It's really annoying and disruptive. If I want pop-ups, I'll download free Mobile apps. I've brought it up to the dev's attention, but he just insists it's reasonable. Not to me, it isn't. Frequent pop-up nag screens are a price of using this software. Disrespectful practice. Uninstalled.
