When I have opened several tabs somethings when I click on one of them it opens in a second copy of Firefox
I have my Firefox set to open to eight homepages. Sometimes when I click on one of those tabs, instead of seeing it in the current copy of Firefox, a second copy of Firefox opens to display it. The tab I wanted is in the second copy and disappears from the original copy, so I have two copies of the same browser running, one with only one tab, the other with the other seven tabs.
I end up closing the second browser, and opening the missing page again, but it would be nice if I could avoid this extra step.

Make sure you do not drag a tab slightly down in the browser window while clicking the tab. Current Firefox versions have a feature called tear-off tabs. You can detach a tab from the current window and open it in a new window by dragging a tab slightly down in the browser window. There is also a "Move Tab(s)" sub menu in the Tab bar context menu that works with multiple tabs selected. You can drag that tab back to the tab bar in the original window to undo this detaching if this happened by accident.
