If FireQuery enabled, the dev tools (inspector) of firefox is reloading a second time if opened

[kapsiR]

Firefox 45.0.1
FireQuery 2.0.1

If loading the inspector via F12 and FireQuery-Addon enabled, the inspector is "blinking" - seems that it's loading a second time.
This is annoying because it's loading time is much more longer than without the addon enabled (and it's done twice)
