When I do Ctrl + Click on a Firefox tab, the display in the tab includes an asterisk (*) before the page name.

What does this signify? Does this have any special significance?

    I don't see it. Are you sure no extensions are involved? – Der Hochstapler Jun 8 '12 at 9:48

    I have Tab-Mix Plus installed. (As suggested in the Answer). – Hashken Jun 8 '12 at 11:15

This is part of the Tab Mix Plus extension.

The default defined action for Ctrl + Click is Selects the tab for merging. You can then merge tabs into one window with Ctrl + Shift + U. Tabs selected for merging are indicated with a (*) before the page name (that's an asterisk enclosed in parentheses).

Editor's note: The shortcut used to be Ctrl + Shift + M, but that now opens a firefox dev tool. After extensive online searching for the new shortcut, I had to search the source code of the extension.

  • I never realized Tab-mix plus had such an option. Thank you for the help. – Hashken Jun 8 '12 at 11:12

    For me, on recent FireFox, Ctrl+Shift+M opens the "mobile view". I'm honestly not sure how to cause the merge to happen, given that that shortcut is not available... I don't see any right-click menu option. – jwd Dec 30 '15 at 19:51
