Sorry but your request doesn't make any sense to me. The only interaction this addon can detect is when you doubleclick on a plaintext url. Double-clicking on the tab bar and such is not detectable with an addon, and even if it was, a doubleclick on the tab bar would not tell my addon which url you want to open. Post an issue on gitlab ( https://gitlab.com/Marnes/plain-text-linker/issues ) if you want to discuss this.
