how do I recover tbb/ff bookmarks from a jsonlz4 backup file on xubuntu 24.04?

cross-posted from: https://lemmy.ml/post/16193001

due to reasons I only have my tbb/ff bookmarks saved as jsonlz4 files, 10 backups.

Ideally, I could recover all those including the structure, but Id settle for the urls (and hopefully the names).

thanks
