Fóram Tacaíochta Firefox

I want to transfer all my bookmarks to another pc. I select export to HTML file and save to a flash drive. I insert the flash drive into the second pc then select 'import and backup' and 'import bookmark from HTML' . Then select the Bookmark.HTML on the flash drive and 'Open'. But no bookmarks ever appear anywhere that I can find. How can I get the bookmarks?

I'm trying to load a jsonlz4 backup of 88.4 mb with 1 146 851 items. When creating a new places.sqlite, the majority of the bookmarks inside Other Bookmarks don't have a location url. Like this:

Name_____________| Location

Normal bookmark | site.com My problem_______|

I tried using https://www.jeffersonscher.com/ffu/bookbackreader.html to convert it into html and json. Importing the html into firefox puts everything into the Bookmarks Menu and everything is missing their location url. Opening the html in writer I see that every bookmark does have its location url but as hyperlinks on the names. Restoring the json, 1 time after not clicking the Check/Repair JSON button and another time after clicking it, gives me all the bookmarks in their correct place but the majority are still missing their location urls.

I also tried creating another places.sqlite with my jsonlz4 backup and exporting as html and json through the bookmarks Library. Importing them, separately, into new firefox profiles just gives me the bookmarks that weren't missing links.

Also tried creating a places.sqlite in windows but it stopped before the Other Bookmarks folder, I guess.

I don't know if its relevant but between restarts and shutdows I always have 18 kmozillahelper processes before even starting firefox. I don't know since when they haven been there or if they have increased.

Any ideas on how to restore correcly my bookmarks?
