How can I close only 1 session, without closing all sessions, when running more than one at the same time?

more options

I normally run 2 sessions of Firefox. Currently, I have 3 sessions running. How do I close only 1 session without closing them all? When I choose "File", then "Exit", all sessions close.

Chosen solution

Firefox doesn't run multiple "sessions", you're seeing multiple windows running in the same process. IE runs each window in its' own process, and Chrome runs each tab in its' own process, but Firefox runs all in one process.

Don't use File > Exit, that is for closing Firefox down completely, not for closing just the window you are viewing when you use that command. There used to be a Close Window command in the File menu, but that was removed a few versions ago. You'll need to use the X in the upper-right corner of the window to close that window and leave the other windows open. Or you can use { Ctrl + Shft + W } close the window which is in focus (you are viewing).

OMG! How incredibly easy! I cannot believe that I didn't try that! I must be losing it. "Multiple windows running in the same process", now that is worth noting.

Thank you very much for the help.

Merry Christmas!
