Firefox is opening new windows automaticly most often when I move the curser
Firefox has started opening new windows that show redirect. This happens most often when I move the curser. The problem is intermittent as it seems to stop when you close all the windows at times. Then when you go to a new page it starts opening new windows again.

If this affects a lot of sites randomly, there's a good chance it is caused by an add-on. Try this:
Disable ALL nonessential or unrecognized extensions on the Add-ons page. Either:
- Ctrl+Shift+a
- "3-bar" menu button (or Tools menu) > Add-ons
In the left column, click Extensions. Then, if in doubt, disable (or if obviously bad, remove).
Usually a link will appear above at least one disabled extension to restart Firefox. You can complete your work on the tab and click one of the links as the last step.
Does that shut down the extra windows?
Also recommended:
(1) Visit the Windows Control Panel, Uninstall a Program. Click the "Installed on" column heading to group by date. Then look for any recent unrecognized programs that may have snuck in as part of a bundle. Remove everything you do not know to be useful and trustworthy.

What pages open in the new window?
Are that random pages or related to the link that you click?
