Are you sure that it is the local storage and not the cache? The storage column in the Firefox preferences also includes other data types. There is a known Firefox bug that prevents extensions from clearing data stored with the Cache API: https://bugzilla.mozilla.org/show_bug.cgi?id=1526246

Local storage is cleared on my part, you can test it with this demo: http://jsfiddle.net/ccatto/G2SyC/2/

Not sure how to run/view that demo. Cache is being cleared (C:\Users\Administrator\AppData\Local\Mozilla\Firefox\Profiles\8k367gi5.NewTest).

After clearing LS:

Files also remain in C:\Users\Administrator\AppData\Roaming\Mozilla\Firefox\Profiles\8k367gi5.NewTest\storage\default:

Cache folder - meant C:\Users\Administrator\AppData\Local\Mozilla\Firefox\Profiles\8k367gi5.NewTest\cache2.

It's hard to reproduce the issue without having step by step instructions, I have tried, but the data is cleared on my part. Please share step by step instructions with a jsfiddle that stores data only in local storage, and make sure to refresh the options page or devtools before checking if the data was deleted.

If you do manage to reproduce the issue in a controlled way, please also open an issue for Firefox, because if valid, this can only be a browser bug.
