Comments on: Track estimated cost for your AppEngine site with Firefox add-on

You don’t need to type anything. GAE (production only, not development server) sends HTTP header with cost info only if you’re logged in as app admin (using sign-in via Google’s user service). When you access your app as admin, estimated cost (x1000) should appear in the FF status bar as shown in the image in my post.
BTW, I’m not sure if this works if you access your application through reverse proxy.

I’m dumb. Can you help me figure out how to use your add-on? What do I type in the error console?

Just released add-on update (linked in the original post) compatible with Firefox 3.0 to 4.0.

Can you update it to work with Firefox 4?

The add-on has been updated (v1.1) to show the total App Engine resource usage in the tooltip.

It totally slipped my mind but per request cost and resource usage is already available in Firefox Error Console (I updated the post with this). Yes, I planned to add resource usage totals to the tooltip text; expect an update later today or over weekend.

Neat and simple tool – thank you for putting this together!

The fact that it doesn’t reset between requests makes a lot of sense. But if you wanted to, maybe when you hover over the label it could also include what the previous request’s info was from the all headers (e.g., resource usage too). It might also be nice if the popup included total resource usage from all the headers combined.

I though about it but I’ve found a total quite useful for checking a cost of a use case for example. Beside, this way was simple to implement. Showing just a single request would require a totally different UI approach. Each page loads some assets and can trigger additional Ajax requests so an add-on cannot decide to show just a single request estimate.

Price for a single request can be easily investigated using Firebug’s Net panel.
