title: For Firefox, is there a file size limit for webappsstore.sqlite?
body: <p>I've begun creating web apps that use <a href="https://developer.mozilla.org/en/DOM/Storage#localStorage" rel="nofollow">localStorage</a>, and since the data stored here persists over multiple browser sessions and pages, I was wondering how long this data lasts for? I only need to store data in there for at most, a month, and definitely I do not want it to be stored indefinitely.</p>
  
  <p>So, does the data eventually clear automatically or will I also have to take into account clearing it myself? Also, I'm guessing there must be some security in place, so that I can't just put localStorage.clear() in my code (I'm currently typing this in Firebug when I need it).</p>
