From https://www.reddit.com/r/firefox/comments/6o2lli/why_localstorage_sometimes_doesnt_show_at_all_in/

"Note: I haven't reported it to Bugzilla because it can't be reproduced consistently.

However, if some website has a very large local storage, chances are the storage panel of dev tool bugs out and doesn't show anything.

It's quite annoying."

Seems like an exception is thrown when this happens:
Error reading response to: getStoreObjects                                                                                       protocol.js:1431
