[tbb-dev] How to enable window.performance.timing on TBB

Hi there,

Sorry I have a silly question, currently I'm preparing some timing analysis on TorBrowser and find that it looks like most of window.performance info has been disabled (I think, for security reasons). It returns all 0s for executing script "window.performance.timing", and returns empty [] for executing window.performance.getEntries().

I've looked through about:config, tried modifying

devtools.dom.enabled;true dom.enable_performance;true

but looks still no effect. So where is the proper way to enable performance timing? Thanks.

Yours sincerely, Zhao Zhang
