Smooth Clean Fast Smart Rated 5 out of 5 stars

Well with this add-on you don't need to waste time on "getting a master" on it.
I mean you don't need to set any configuration at all.
You don't need to learn something else.

You just create one folder and you are already doing your job with Js (and CSS too!!).

No waste of memory with slow GUI, you just use your favorite editor.
I searched among all the Js collection and this is the one!

To the author:
I suggest the author to consider to modify the "About this Add-on" overview.
I examined the entire JS Collection 3 times(25 addons at the moment!).
And lucky desperate me, only the third time I noticed that dotjs of course can apply code to every page that you visit.
It is important to know it at first glance.
Instead I used to stop reading at the end of " based on their filename and the domain of the site you are visiting."
This addon deserves to be known! Great job.
Happy to donate to you!
Thanks a lot
