a nice solution comes from

How to Copy URLs of All Open Tabs in Firefox

https://www.howtogeek.com/723921/how-to-copy-urls-of-all-open-tabs-in-firefox/

right clicking opened tab, all opened tabs can be selected
moving via menu to bookmarks/ booksmarks management 
url bookmarks can be right-mouse clicked to copy urls
finally, urls can be pasted into Notepad++
and saved as a file
unfortunately, saving as .html file
fails to generate html file with clickable web links

Notepad++ keeps urls active, selectable but not ready to be opened in Firefox

so I need to learn how to make Notepad++ or another editor to save urls as
html file

BTW

Selecting all opened tabs I get 1,000+ active urls (opened web pages ), so something must be wrong
