User-Agent:       Mozilla/5.0 (Windows; U; Windows NT 6.0; en-US; rv:1.9) Gecko/2008052906 Firefox/3.0

I would like Firefox to display detailed information on cpu/memoru usage per page.
This would help webdesigners and webapplication developers to create slimmed down and fast sites.

Information which would be interesting are;
- page load speed.
- page rendering speed.
- page memory usage.
- page cpu usage (for rendering and currently executing scripts)
- plugin memory usage
- plugin cpu usage

Thanks.

Reproducible: Always

I think page load speed and page rendering speed would be pretty useless for most users. You can also use Firebug with the YSlow plugin already if you need it. There's also a difference in actual rendering speed and perceived rendering speed.

Memory and CPU usage on the other hand could be useful.

about:memory is filed somewhere, but most of this is Firebug territory, not core app.

Oops, I should have marked bug 380521 as a dup of bug 400120, not of this bug.
