localstorage available after upgrade

I have an extension with a fair number users and it uses localstorage to store the开发者_JS百科ir information. When I put a new version out, will the localstorage remain?

Thanks

Local storage will remain in clients' local machines. However, you should keep in mind that users can clear their local storage data easily. Local storage is also limited to 5MB.

Yes, that's the whole point of localStorage.
