Sorry, not sure where to put it for the "topic". Tried this link: https://support.mozilla.org/en-US/kb/recover-user-data-missing-after-firefox-update I see TWO profiles listed. As the current one isn't what I want I try the second one "launch in new browser" - as said in the notes. All that does is throw me back to the "welcome to Firefox" page. No, it isn't the end of the world, but I had a few open windows/tabs. (By comparison to this machine which has A LOT of windows and tabs open) They were useful/used/needed stuff. It is a DIFFERENT MACHINE to this one. I haven't logged in here from the OTHER machine - may in the future if required/asked. I'll try to leave well enough alone for now, but I do need that machine and this is a huge bump in the usual smooth flow of things. BTW - just mentioning. MANY sites showed/suggested how to restore previous sessions but they all point to the HISTORY menu and then show RESTORE OLD SESSIONS. Doesn't exist on either of my machines. No data shared as this is NOT the machine with the problem.
