Dear all, I would like to know whether there is any way to load (some/any) sidebar content (e.g., for the sidebar created by the "Notes for Firefox" extension) as a "large version" into the main browser window? I was already able to extend the maximum size of the sidebar on one hand and on the other hand I even extracted the files of the "Notes by Firefox" extension whose sidebar I would like to have open in the main browser window. Unfortunately, just loading the "sidebar/index.html" (as this is the "default_panel" of the "sidebar_action" mentioned inside the "manifest.json" file of the "Notes by Firefox" extension) did not work as some (a lot?) of variables are not defined... So, is there any sort of way to get some sidebar being displayed in the common browser content window? If so, please advice how to do it. Thank you! Best regards, Patrick
