does this error affect my code.?
<p>i m getting error in firebug console</p>

<pre><code>uncaught exception: [Exception... "'Invalid save data.' when calling method: [nsIDOMEventListener::handleEvent]" nsresult: "0x8057001e (NS_ERROR_XPC_JS_THREW_STRING)" location: "JS frame :: chrome://firebug/content/spy.js :: callPageHandler :: line 744" data: no]
</code></pre>

<p>When i put this code</p>

<pre><code>value = key+'^_^'+value;
</code></pre>

<p>But when i modify this code and put</p>

<pre><code>value = key
</code></pre>

<p>the error removes.</p>

<p>so does this error affect my code?</p>
