Nvm it's fixed

The robot icon and diagonal stripes in the address bar indicates Firefox is being remotely controlled by other software on your computer. Hover your mouse cursor over the robot and a tooltip will appear giving a reason. One way this can happen is if you start with the -remote-debugging-port command line argument. If you are unsure, you should scan your system for possible malware.

Note that this is usually caused by a user.js file that sets some prefs.

• user.js => remote debugging:
  devtools.debugger.remote-enabled = true
  devtools.debugger.prompt = false

Removing this user,js file in the profile folder and resetting affected pref via about:config should fix this.
