Can you check u'r website for weired stuff Rated 5 out of 5 stars
I clicked on your website and it popped up a page with huge progress bar, as if scanning for virus....popped up a dialog box asking me to 'restart system'. The status bar had a hard to read url something like xv.network. Think your (or partner) server has a virus in it. Couldn't get all the details as I killed firefox quickly.
Gave 5 stars...as I haven't tried your add-on and its not a review, but AMO wouldn't let me post this without marking star rating.
