So you don't wan add ons because you apparently got a virus that you attribute to them:
I don't really want add-ons. It invites hackers to create add-ons with reactive keyloggers, which I sorely do not want. Ever. Again.
Then you admit that it wasn't the add on, it was the method in which you obtained it:
It's never the actual thing that's the problem, it's acquiring the actual thing.
And then... You call yourself stupid?
Users. Stupid. A coexistence that is directly relative to the level of knowledge one pertains in the field at hand.
What was your problem with add ons again?
Gosh, your words are pretty, but your thought process is borked.
