NS_ERROR_ILLEGAL_VALUE exception in Firefox for large datasets

[Ciki]

storing all snippets in cache might cause the HTML5 pushstate cache to overrun Firefox's 640k character limit.

Might it be better to use localStorage or sessionStorage for this cache, as Mozilla's documentation suggests?

I agree with @Ciki . Using localstorage by default and then falling back to the current method seems entirely reasonable.
