In this version the UI has changed a little. Now multiple filtering rules can be set, although the system for setting them is a little archaic.  As can be seen in this screenshot:

Multiple Rules alowed

The activation mechanism stays the same, and so the quick search in the net tab. But now there are two buttons, to remove the applied filters (in case you want to view all the results) and one to apply the stored rules.

New buttons in the net panel

You can grab this release from the releases folder. Also keep in mind that I'm trying to set up an upgrade channel in this webpage, so you can install once and then get the updates automatically.

The aim of this extension is to let you add custom filters to the requests listed in the Net Panel. Right now this is the first... nightly. It isn't even an alpha, I just made it work, and then packed and uploaded it. So don't expect it to be a lot friendly, it just works.

To use this extension you should have Firebug 1.5.0a21, 1.5X.0a21 or the latest SVN revision, since it depends on a listener added in a21. Just go to releases and install the xpi.

How to use it

• Install the extension and make sure the dependencies are met
• Go to the Net Panel
• Press "Advanced Filters", a prompt should appear
• Enter the desired RegExp pattern against you want the request's URL to be tested.
• Reload the page, now as long as the "Advanced Filters" button is selected, your requests will be filtered. To disable the filtering, press again in "Advanced Filters".
• You can change the applied filter pattern by disabling and then enabling the advanced filtering. Each time you enable the filtering, a prompt will show up in wich you can enter the new pattern. Then it'll be applied to the monitored requests.
