Works really well

Didn't work as you wrote it btw, when I clicked on "Run Extension" it didn't work.

I used to play around with the inspect element, this is much easier to use.

Tried using it, it didn't work, not recommended.

ease of use is great! It does let you edit protected things but it doesn't allow them to be copied to the clipboard. I didn't use it much but it works well for the 40 seconds I tried it.
