Firefox Developer version and firebug 3.0 failed install of add-on

I have developer version installed (44.0a2) with firebug 2.0.13 plugin. When I right-click on the webpage and select "inspect element with firebug" I get a pop-up asking me to install firebug 3.0 beta. when I click "install and restart" I get an error message saying the install of firebug 3.0 failed.

When I try to install firebug 3.0 manually - firebug-3.0.0-beta.1.xpi I get a failed install due to add-on not verified. I am getting the firebug 3.0 xpi from https://getfirebug.com/releases/firebug/3.0/

Can anyone help with how to install firebug 3.0 with the developer version of firefox?

I had this problem today. It is because by default firefox is not allowing unsigned plugins, which firebug 3 is because it is still beta.

To disable extensioning signing type about:config in the address bar

  • search for xpinstall.signatures.required
  • Right click and toggle it to false
  • This should allow it to install.

The alternative is disabling multiprocess firefox so that firebug 2 can still work. This can be done by disabling multiprocess firefox in the settings menu.
