 > Yes, but Firefox is an integral part of your product, so this is your
 responsibility to push such bugs forward to Firefox instead of wontfixing
 them.

 like your configuration problem than Firefox is inherently much more
 slower on Windows.

 machine you have gets strained in "standard" mode.

 then it doesn't look like hardware problem.

 calculated side-effect.

 displayed.

 I just closed it on our side indicating that we won't fix it as part of
 our Tor Browser work. May I ask you to file a bug at Mozilla's bug
 tracker, so they get the underlying problem on their radar and provide a
 fix we then can backport? I think it's useful if they can get back to you
 directly if they have questions instead of me or us proxying the whole
 conversation the whole time. Thanks! (Please note the filed bug on this
 ticket then)
