57.0b11 (64-bit) Developer Edition ─ DOM inspecting WebExt?

Post by JZerscje »

Is it possible to use the Browser Toolbox to inspect WebExtension add-ons? I've noticed that I can only inspect elements of the Browser, but a addon sidebar isn't selectable.

Pick an element from the page button doesn't seem to work correctly in the sidebar.

Try opening the sidebar page in the main window, then troubleshoot like normal.

e.g. moz-extension://<UUID>/sidebar.html

The UUID is randomly generated for every browser instance.
