Dev Tools tab not showing on DevTools by default

[ghost]

Feature Request While using the boilerplate and adding the Dev Tools Tab feature I expect seeing new tab added to dev tools, but its not implemented. By default, I think it should contain a default placeholder tab which works with the mozilla polyfill.

To Reproduce

• vue create extension
• vue add browser-extension
• at Which browser extension components do you wish to generate? mark Dev Tools Tab
• npm run serve
• open chrome on macOS and load unpacked
• press F12

Expected behavior my new extension's devtools should appear as a tab
