Intercept popup windows and force them into a tab of the main window. Options to select only the URL's that you would like.
Want to prevent popup windows from loading in a separate window and instead load into the main window? This extension allows you to selectively choose which popups load into one window by type the URL web addresses in the settings. When it sees a popup with that URL it will intercept it and move it into the main window as a new tab. Deliminate the URL's with a hash tag/pound symbol (#)
