Firefox does not "Open previous windows and tabs" [Solved]

[LinnitXa]

In the past few days I find Firefox 127.0 (recently updated in mx updates) is re-opening without any of the previous windows and tabs. I have selected General > Open previous windows and tabs, but it doesn't work.

At the same time the Bookmarks Toolbar opens empty. I have to open bookmarks sidebar to access.

While I wait for Firefox to sort this out I have created a current tabs folder to which I save any open tabs.

Today I re-booted and the previous session's open tabs were there, and the Bookmarks Toolbar is showing again.

All very mysterious, but I'll mark this Solved.
