i do not want to use Firefox Sync.
i have saved my bookmarks from my desktop Firefox to a HTML file.
i have sent the HTML file from my desktop to my Samsung Note Tablet.
can i, or how do i, IMPORT the HTML file contents into Firefox on the tablet ?
There is no way to import html bookmarks backups on Firefox for Android.
You can consider to create a second profile on the desktop computer with only those bookmarks and set up sync with that Firefox profile folder if you do not want to sync all bookmarks.
