New Tabs Randomly Moved To New Window, Why?
Upon opening a new tab it will sometimes get moved to a new window. Just now as a matter of fact I was opening 4 new tabs in succession. When I opened the final fourth one I clicked back to the main tab (#5) & immediately all following tabs were moved to a new window. Why does this sometimes happen & is any 1 else having the same problem???

If you drag a tab away from the tab bar, it will "tear off" and become a new window. Could it be that you are accidentally the dragging the tab slightly when you click on it?

How do I disable tab tear off?

Okay, so how do you get the dang window BACK to the tab position??
You can detach a tab from the current window and open it in a new window by dragging a tab in the browser window.
You can drag that tab back to the tab bar in the original window to undo that detaching.
