Restore Firefox Bookmarks

When I attempt to restore bookmarks from the bookmarkbackups folder in Firefox via Bookmarks -- Show All Bookmarks -- Import and Backup -- Restore, I get "Unable to Process the backup file." How do I correct this? Is there another way to extract the bookmarks from the .jsonlz4 files?

Thanks.

sudo apt install lz4json jq

lz4jsoncat bookmarks-*.jsonlz4|jq '
..|objects|select(has("typeCode"))|select(.typeCode==1)|
{title:.title, uri:.uri}'

Cool! Thanks a lot.

Now I'm trying to recover logins and passwords. Do you have any more magic commands that will accomplish this?

Install and run nss-passwords.

Thank you, Shruggy.
