how to empty firefox dom localstorage

Question

I'm trying to clear my local storage in Firefox 13.0 so I can continue using Lawnchair.

In Firebug [Dom] tab, I have been manually deleting properties from 'localstorage' key, but it takes about 10 seconds per delete (only 454 * 10 seconds to go!). (I hoped I could release enough space to let Lawnchair.nuke() do its job, but haven't been able to so far.)

I tried visiting about:config to turn off and back on localstorage but that didn't delete what was in there.

How can I mass-delete local storage for one website in Firefox?

Answer 1

Open the built-in console, CtrlShiftK (it's faster than Firebug), and paste the following code:

while (localStorage.length) localStorage.removeItem(localStorage.key(0));

This snippet will delete all localStorage key-value pairs on the given website.

Answer 2

localStorage.clear(); // Capital S is required.

This will clear all key-value pairs.
