how to delete imported list of tabs

[dutyhog]

I bought a previously-owned 2018 Mac MIni with a clean install of OS 15.2
I installed and started FF134.0, found its Profile folder, exited FF and copied in my FF profile from my old MacBookPro which was running under Mojave.

I reopened FF and used it for a week or so.

Then I remembered TST and installed it today, 11 Jan 2025.

The tree looks OK, with my open tabs displayed as expected in the sidebar.

But the list of all tabs is what was on my MacBookPro. There is also a list of all tabs in window 2 and a window 3, but I don't have any extra windows on this computer. It has taken these from what was on the MacBookPro.

Do you know which files to delete in the FF Profile folder to remove the legagy data?
