lz4jsoncat - decompress tool for mozilla lz4json format
lz4jsoncat somefile.mozlz4 > somefile.json
lz4jsoncat can unpack lz4json files as generated by Firefox's bookmark backups and session restore. The data is dumped to stdout.
The input file must be mmappable - so you can't use a pipe here. 2018-12-25 lz4jsoncat(1)
