Firefox extension that writes to its own log file

Question

After a whole day figuring out how to write something from my browser to a local text file.. Im thinking of something like for example a Firefox extension that has a log file.

Is there any way that my extension can write to my extension. Means, inside my extension got a log file.

For information I'm developing for Linux platform.
