Recently I have been coming across annoying Share This pop-up windows on several of the blogs that I read. If you happen to leave your cursor over the link for a second or two, a window pops up and obscures part of what you are trying to read. If you use Firefox there is something you can do about it:
- Install the Adblock Plus add-on (if you haven't already done so)
- Open the Adblock Plus Preferences window: Tools > AdBlock Plus Preferences...
- Click Add Filter...
- Enter http://*.sharethis.com/*
- Click OK
There, a whole business model obliterated!
