        	 Handling JavaScript Popups 
When you come across a site that executes a javascript open new window function, and if the popup window is without all the usual window features, i.e. back/forward/reload buttons, status bar etc, Firefox will automatically treat it as a popup and will not open it as a new tab. However, if you find this to be a nuisance and wanted to open all new windows in a new tabs, you can specify it via the 
browser.link.open_newwindow.restriction setting.
Config name: browser.link.open_newwindow.restriction
Default: 2 – Open all JavaScript windows the same way as you have Firefox handle new windows unless the JavaScript call specifies how to display the window
Modified values:
    * 0 – open all links as how you have Firefox handle new windows
    * 1 – do not open any new windows
    * 2- open all links as how you have Firefox handle new windows unless the Javascript specify how to display the window
