Whats wrong? Firefox?

So today I woke up and came to 4 chan. I visited /b/ and it was all fine. When I went to /v/ and /a/ it didn't show any of the thread images. I got angry and I installed opera. What's wrong with firefox????

You right-clicked on a picture in 4chan and chose "Block images from this site". Go Tools+Options, Content tab, click Exceptions right of "load images", and remove 4chan from the list.

Installing Opera is the smartest thing you've ever done.
Furryfox sucks.

I'm surprised Firefox doesn't ask you first.  It seems weird a browser designed for idiots wouldn't give some "Are You Sure?" warning.  Even Mozilla asks me if I'm sure I want to set an image as my wallpaper.
