I was able to add - but IMHO it does not work.
Dashboard and logger field in about:addons do not work for me.
When I try to error console on it => browser crash. And PC starts to labour.
After the crash the mentioned fields are not functional/partly invisible.
That the console is not usable is a show stopper. At least on my 10 years old PC.

p.s. I suppress compatibility checking.
