I feel you, while the debugging option is handy for development, it is annoying that you can't easily install the extension permanently. The way I do it now is to package the extension as zip (no webext needed) with a custom manifest, which can be installed by setting xpinstall.signatures.required to false in the about:config page. On the manifest side, you just need to include this snippet: "browser_specific_settings": { "gecko": { "id": "example@gmail.com" } }
