Acts like malware. Rated 2 out of 5 stars
YOU HAVE NO RIGHT TO HIJACK PEOPLE'S BROWSERS, SO STOP IT !!!
At the VERY LEAST, give folks the choice of whether they want to see your update page; but DO NOT simply MAKE us have to see it (can't you see how this resembles browser hijacking ?!).
I would give this add-on a better review but for 2 things: It behaves like malware (see above), and it is NOT the only option nor even the best that I have found.
