Not that anybody bothered to answer my question here, but I found a solution and sharing below in case anyone facing a similar problem needs help. First, open your Firefox account on Desktop Open this: https://support.mozilla.org/en-US/questions/1293198 see the last comment under it by user "cor-el" which mentions installing the About Sync extension. Install that extension, then close Firefox and then open it again (I've read that the extension doesn't work if you don't restart Firefox) write about:sync in the address bar, hit enter open a new tab and go to this: https://stackoverflow.com/questions/50829318/export-synced-tabs-in-firefox Follow the instructions on that page. As it says on that page, copy-paste the list of your tabs in MS Word or Notepad or whichever text-editor you prefer.
