Is there any way to start automatically the Firebug/Inspector after starting Firefox/Chrome?
In Firefox you can set Firebug to be always on by opening about:config and setting extensions.firebug.allPagesActivation to on.
Note that this will have Firebug always active and recording -- which you can see by the Firebug icon being colored -- but the panel may be minimized. Show it by clicking the icon or using the hotkey (Usually F12 but sometimes CtrlF12).
Note that the valid values for extensions.firebug.allPagesActivation are:
- none -- (default) Page-by-page settings may apply.
- on -- Firebug is activated for all URLs.
- off -- Firebug is never activated.
As far as I have been searching it is not possible to do that in Google Chrome. But you can use the shortcut ctrlshiftj to open it immediately. Hope it helps!
