Hi! I'm developing a web extension. I managed to install it via about:debugging "temporary extensions", and I can see the extension icon under the "puzzle button" in the toolbar. I now want to pin it to the toolbar, it will save me a click when I'm trying to test things live. When I click the puzzle button, there is no "pin to toolbar" option for the temporary extension, although I can see it for the extensions installed from the marketplace. Is there a way to allow pinning for the extensions installed for debugging? Maybe an option in "about:config"? Thank you!
