# dejsonlz4
|
||
|
|
Decompress Mozilla Firefox bookmarks backup files
|
||
|
|
|
||
|
|
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) [1].
|
||
|
|
|
||
|
|
## Usage:
|
||
|
|
```
|
||
|
|
Usage: dejsonlz4 [-h] IN_FILE [OUT_FILE]
|
||
|
|
-h Display this help and exit.
|
||
|
|
Decompress Mozilla bookmarks backup file IN_FILE to OUT_FILE.
|
||
|
|
If OUT_FILE is '-' or missing, decompress to standard output.
|
||
|
|
```
|
||
|
|
|
||
|
|
## Build:
|
||
|
|
- `gcc -Wall -o dejsonlz4 dejsonlz4.c lz4.c`
|
||
|
|
|
||
|
|
## Windows note:
|
||
|
|
- `dejsonlz4` on Windows does not support unicode path/file names at this time.
