I worked successfully with Firebug v2.0.19 under 32bit Firefox v55 and Win 7.
A couple of days ago I upgrade Firefox to v56. When I open now a webpage and right click "as usual" on a certain text line then select "Inspect Element with Firebug" then Firebug opens (at the bottom) with the two well known subpanes. However always the left subpane is empty. The right subpane is sometimes empty. Why does Firebug v2.0.19 not work any more? Is it because of Firefox v56? Is there a workaround/newer version of Firebug? Ben -- You received this message because you are subscribed to the Google Groups "Firebug" group.
