I\'ve been working in a web application and I\'m using local storage. But for some Firefox users I notice that they\'re having the following error:
NS
After an OS crash files within the Firefox profile folder might be corrupt and lead to non-functional websites (in my case ironically the Firefox marketplace). Here, webappsstore.sqlite
was affected.
As user @Oli stated over at Ask Ubuntu
Firefox stores its HTML5 data in a file called webappsstore.sqlite. That's sitting in your profile directory which lurks somewhere in ~/.mozilla/firefox/....default/ (depending on what your profile is called).
Move that out the way and restart Firefox and everything will come back to life.

If deleted/moved out of your profile folder, Firefox builds a new, sanitized webappsstore.sqlite
file. Worked for me.
Information on where to find your profile folder can be accessed here.
