I have a window that pops out everytime I open firefox. It is not a pop out window per se but one the says "open" or "save" the file px.php from http://adnetwork.buzzlogic.com. This pop up looks like the normal pop up that you get when you download files from the internet.

I tried cleaning out my history, cookies but it still happens. I uninstalled and reinstalled firefox but it sitll pops up.

Help Please!!! I could not find information on how to fix this online.

You can check the homepage setting.


This can also be a problem with the files sessionstore.js and sessionstore.bak in the Profile Folder

Delete sessionstore.js and sessionstore.bak in the Profile Folder

If you see files sessionstore-##.js with a number in the left part of the name like sessionstore-1.js then delete those as well.

You will have to redo App Tabs and Tab Groups after deleting sessionstore.js.
