how do i reattach tab that came off page
Tabs often become detached from main window and open in own window. How do I get tab back onto main window?

In the other window click and drag the tab and drop in the main window, and the tab will transfer to main window and the other will close:
Make sure that you do not drag a tab slightly down in the browser window while clicking. Current Firefox versions have a feature called tear-off tabs.
You can drop the tab on the tab bar in the window where it got removed.
