Sometimes it works, and sometimes it doesn't. It also it keeps sending annoying pop-ups asking me to rate the add-on and to review it (even after I've posted a review. Each time that annoying pop-up appears, I've lowered its rating by another star lower (I can't go any lower now!), I need to uninstall it, because I think that there are better, similar add-ons that don't interrupt you and bug you all the time by constantly asking you to rate them, and those better add-ons also probably more consistently work better.
