Looking for a killer javascript/website monitoring/debug tool
<p>I'm looking for a good way of monitoring and logging full exchange between website and the internet.</p>

<p>I know that this can be done with firebug. The main problem I have with it is, that it cannot persist log data over reloads.</p>

<p>Also, if would be very cool to have an ability to log javascript activity and filter the log by the action I'd like to debug (e.g. setting a cookie, change of attribute etc)</p>

<p>Does anyone know something that fits at least some of those requirements, and on the rest performs at least as well as firebug does?</p>
