So I was short on storage on my archive drive. I saw librewolf source code. It was tar.gz and ~800MB. I uncompressed it then recompressed it with bzip2 -9 and now it's ~600MB. Generally #bzip2 has better compression for such these data than #gzip.

Edit: But don't do bzip2 -9 all and everywhere. Sometimes -4 is the same as -9 however the latter being tons slower. Also there is pbzip2 for using all your CPU cores.
