I going to copy over Win 7 docs etc to a new Passport Storage unit Ext Side-Drive. I Saved FF bookmarks in my Win - 7 Doc Folder. When I start up my Win 10 new computer, will it migrate from the Ext Hard drive ok over in the Windows -10 Doc folder saved in my older computer and open ok to be pasted into the bookmarks dropdown on FF ? I had a lot of trouble going from XP to Win 7 last time with Firefox and didn't all move over for me.

Thanks.

You can copy/backup files like these from the current profile folder with Firefox closed and transfer them to another device via a UBS stick (jump drive).

You can use the button on the "Help -> Troubleshooting Information" (about:support) page to go to the current Firefox profile folder or use the about:profiles page.
