firefox pop ups

hi all,



whenever i use firefox, i keep getting ads that pop up on the left and right part of the screen. It is so annoying. Whenever I use safari, on the exact same pages I do not have that problem.



I have gone through the settings, but I can't figure it out. Does anyone know how to eliminate those ads?



Thanks
