When I click on a link/button at a website that is coded to open in a new window, that window opens within another window There are two ribbons for minimizing/closing the window, and the back and forward buttons don't work. There are no tabs. When I click to open a new tab, that tab appears and the previous page forms a tab, but doesn't show a URL and when I drag it to the main window to combine tabs, it appears blank. I used to be able to drag new windows into my main browser so I could have just one browser running at a time. Since I installed Firefox 5, I haven't been able to do that. They no longer open up with a tab I can drag. Suggestions on how I can fix this?
