About a year ago (since I downloaded and installed Avast 8.0) my Facebook page began opening with images overlapping one another, various links did not operate, notifications would not open, and so on. I can log in to Facebook on my husband's computer (which uses no virus application), but would rather use my own laptop. We are running Firefox on both computers. I have tried disabling all Avast functions, but the Facebook anomalies remain. If the solution to this problem is complicated (such as making system changes to my MAC), I'm not enough of a techie to accomplish that sort of thing. I recognize the fact that this is an Avast forum, and do not wish to attempt a "Facebook" discussion. If anyone has a simple suggestion, such as uninstalling Avast or logging out and then back in to something, I'm willing to try and will appreciate your patience with me.
