"Storage" function slows down form submission in Firefox

Here is simple submit button which submits form:

<!DOCTYPE html>
<html>
  <head>
  </head>
  <body>
    <form action="action" method="POST">
      <button type="submit">Submit</button>
    </form>
  </body>
</html>

In Firefox 45 (updated from 43 where problem was also present) it takes a long time to submit a form. After inspecting in developer's tools what takes so long I found it's "Storage" function. Here are screenshots presenting the problem: Storage 1 Storage 2

This problem does not occur in other browsers, so the question is why does "Storage" function take almost 1 sec after form submission, making it look like long submitting (may it be because a lot of tabs are open) and how to fix it? Also why is it invoked? In Firefox Developer Edition this "Storage" function is not present.

After using the profiler addon suggested by the8472 I found out it was because of Lazarus: Form Recovery addon which saves inputs from submitted forms. For interested there is a screenshot: Lazarus

After disabling this addon everything works fine, like in other browsers.
