When you refresh (reset) Firefox, everything is removed. Bookmarks, History, and Passwords are copied to a new profile, and the old profile is moved to your desktop into a folder labeled; Old Firefox.

Look on your desktop. Do you see a folder called; Old Firefox?

Refresh Firefox - reset add-ons and settings

If you're having problems with Firefox, refreshing it can help. The refresh feature fixes many issues by restoring Firefox to its default state while saving your essential information like bookmarks, passwords, and open tabs.

Thanks Fred - and yes I did find the Old Firefox Data folder on my Desktop. I've opened the Morning Coffee folder in that, and am presented with a list of Upper Case letters each of which opens a url. I'll have to plough through those to find the odd one or two which didn't transfer themselves from Morning Coffee in the old profile to the Most Visited list on the new. For now I can live with (I don't seem to have much choice in the matter as fixes suggested elsewhere look like a lot of work LOL) this solution. But I still wonder where the "Make this page my Home Page" is now to be accomplished. (In my old profile that was the opened Morning Coffee with all its Tabs) Cheers.

The developers should not have renamed that item to "refresh". Its older name was "reset", which is what it does to Firefox. https://support.mozilla.org/en-US/kb/refresh-firefox-reset-add-ons-and-settings

finitarry, I very much agree with you. The name is misleading.
