Config Button

Adds a Config button, opens about:config (aka Config Editor or Advanced Preferences) in a tab.

Version 2 always opens about:config in a tab, an option to open about:config in a dialog may be added later.

ESMified the add-on.
Set minimum version to Thunderbird 115.0.
Set maximum version to Thunderbird 136.*.

Some add-ons ask for permission to perform certain functions (example: a tab management add-on will ask permission to access your browser’s tab system).

Since you’re in control of your Thunderbird, the choice to grant or deny these requests is yours. Accepting permissions does not inherently compromise your browser’s performance or security, but in some rare cases risk may be involved.
