Vue devtools plugin V5 not working with Vue 3: install plugin V6 (beta)

Even though Vue 3 was relased in september 2020 the current vue devtools plugin v5.x does not work with this version (the devtools panel does not show up when debugging a vue application).

You can install the beta for the v6 version to get some browser debugging support:

1. Remove the old devtools plugin from your browser if present
   
2. Go to the beta release channel
3. In the assets at the bottom of the latest beta, click the vuejs_devtools_beta-6.0.0.xx-an+fx.xpi link

Good bug hunting with Vue 3!
