From recovery.js to recoveryjsonlz4

[Cecil Westerhof]

I have a script to get the number of windows and tabs that firefox
uses. It always used a file recovery.js, but it changed to
recovery.jsonlz4.

Looking at the extension I would think it is an lz4 compressed file.
But when I use:
    import lz4

I see that it is deprecated. How should I work with this file?
