In Safari, the blur effect should not extend over the boundaries of the object.

Is that a bug or a feature?

Btw, there are some interesting ideas for sliding captchas.

I've used the filter effects for a lot of really useful applications. I'm always surprised though that sepia is an offered filter. It seems pretty kitsch and not that useful, it is effectively grayscale with an additive color overlay of only one color. I don't mind that it is there, but it doesn't seem like a primitive operation like the rest. Perhaps if you could change the overlay then it'd be a lot more useful.

There overflow: hidden; on one of the its parents, so you'd assume that it shouldn't blur outside of the parent container. I'd call that a bug.

Is there any difference between opacity and filter: opacity ?

As far as I know, there's no difference in the outcome. Opacity is handled by most browsers through hardware and I would imagine the filter method does the same. I would hope they are handled the same because it would seem wasteful to have two methods that do the same thing.

Somewhat useless thought, opacity and the opacity filter can be combined on the same element. If one is set to zero it makes the other irrelevant. If one is set to 100% then it makes itself irrelevant.

Earlier quoted context omitted.

Works on ff 37.0.2

And on Firefox for Android. Blur is very slow, though.

Could be that the blurring isn't being handled by the GPU. CSS 3D-transforms are usually added as a work-around when we want a smoother performance for certain elements by forcing that extra rendering step.

These are cool, but seems like in cases where you want to blur something out on an image you should do so in photoshop on the actual image and not with css. Otherwise someone could just use element inspector to delete the blur effect.
