Description Keshav Kini 2012-11-18 02:14:07 UTC
As of Firefox 16, there's a built in profiler framework in Firefox, but it
needs to be enabled at compile time. See
https://developer.mozilla.org/en-US/docs/Performance/Profiling_with_the_Built-in_Profiler .

It would be nice if we could have a USE flag to enable this.

I don't have any familiarity with how Firefox is packaged for Gentoo, but I did try to make the following changes to the ebuild:

After this change, Firefox seemed to build without errors, at least. The extension at https://addons.mozilla.org/en-us/firefox/addon/gecko-profiler/ still shows as "Not available for your platform", though.

If you feel I have closed your bug and it is still a current issue, please reopen and update it completely. We will not work bugs that have no ebuild in tree any longer or can not be reproduced with a current system.

Thank You for your support and understanding
