How do I block a popup window that I have allowed to open on Firefox once? I now have the popup blocker set to block all sites, but the popup still opens every time I open Firefox or open (sometimes) a new tab.
How do I block a popup? I allowed this popup to open once. Now I have set the popup blocker to block all sites but this popup still opens every time I open Firefox and sometimes (usually) when I open a new tab. I Have stopped and restarted Firefox multiple times. I have rebooted the computer. I have set the tools/options/content/block pop-up windows/exceptions to block all sites (no exceptions). I have no other issues with Firefox. I have Adblock plus (with (1) subscription) installed I am currently using Firefox version 4.0 on Windows7 Ultimate.
