Firefox keeps crashing
I have windows 7 and my browser is Firefox 20.0.1 which is the current update. Lately Firefox crashes but I can get it back. I have no idea why this is happening. Any ideas?
Also while I am in Firefox a popup (which goes behind the page I am on) from MSN Survey comes up. I have adblock plus but it keeps coming up anyway. I don't understand why I am getting a MSN Survey. MSN is my homepage and has been for years, this is the first time I have gotten one of these Surveys that keeps coming back. These two things happen while I am in Firefox. That is why I posted these two problems since they both relate to Firefox.
I have run Malwarebytes and nothing shows up as Malware.
I would appreciate some help with much thanks in advance.
