Does anyone work with layout on flex boxes in Firebug?

Question

css

We are developing a project only for Firefox. The layout actively used display: -moz-box. Recently, in connection with the transition from version 3.5 to 29, they tried to transfer all this to display: flex. And faced with fierce brakes Firebug'a. It is not possible to localize the problem, it seems that the brakes depend on the number of flex boxes on the page, but Firebug reacts especially unfriendly if it comes across a block with position: fixed inside the flex box - the browser process starts to load the processor much more than usual and periodically the entire page, except body disappears for a fraction of a second. At the same time, when Firebug is closed and in the Inspector built into the browser, there are no problems.
Perhaps the problem is related to a known bug in Firebug .
Actually, the question is, has anyone observed this?

Use a browser from the corporation of goodness and you will be happy.
