You could file a bug:- via the address bar, go to about:config > click 'Copy text to clipboard' > paste to a text file and save it- via the address bar, go to about:memory > click 'Measure and save'- file the bug at https://bugzilla.mozilla.org/enter...
If you don't see it, then it doesn't exist and would have to be added to the base code. You should post the idea at https://connect.mozilla.org/t5/ideas/idb-p/ideas.
