Unlike some people who don't want to see the extension name in the address bar, I want to see the *entire* extension name. Threat model: one of my extensions gets a rogue update and puts up a screen that looks just like a screen (e.g., the login page) of another extension (e.g., my password manager). When the extension name is too long, Firefox currently displays: Extension... <last word of extension name> To be secure I currently need to click on the above so that it expands, in order to verify it's the correct extension. Can this be done in CSS, or would a feature change be needed to Firefox?
