When do I load a browser frame script (e10s)?

best option for firefox extension to keep panel / overlay / sidebar visible between pages?

Firefox addon uploading canvas contents to imgur

This depends on what your add-on is actually supporting via em:targetApplication. Usually having an application= is not required, because there simply is no ambiguity.
