In theory, you should be able to strip the first 8 bytes (e.g. With dd if=original.jsonlz4 of=stripped.lz4 bs=8 skip=1) and that should leave you with a valid lz4 block. Note that this is distinct from a lz4 frame. Recommended software programs are sorted by OS platform (Windows, macOS, Linux, iOS, Android etc.) and possible program actions that can be done with the file: like open asd file, edit asd file, convert asd file, view asd file, play asd file etc. (if exist software for corresponding action in File-Extensions.org's database). Current Firefox bookmarks backup files are stored as non-standard file format based on lz4 compression. These files have a.jsonlz4 extension. Use dejsonlz4 to decompress them. Lz4.c and lz4.h at this repository are verbatim copies from the Mozilla repository as of 2016-05-12 (as currently used by Firefox). Firefox creates frequent backups of your bookmarks. Automatic backups are compressed using Mozilla's flavor of LZ4 compression (.jsonlz4 file extension), while backups you create yourself (in the Library window) are not compressed (.json file extension by default). This tool can convert a backup file to the HTML export format. Step 1: Load File.

Files with jsonlz4 extension are in most cases compressed bookmark backup files from Mozilla Firefox internet browser.
