Javascript weirdness

Whichever browser you use, have you ever noticed that sometimes due to bugs, when you click on a button the browser just ignores the javascript behind the code. I have seen the same bug on the old Opera(Presto), Firefox(Gecko), Chromium(Webkit/Blink), so it really seems to be a case of bad web development which seriously annoys me.

I find it happens a lot due to not allowing xss, cookie permissions, sometimes https. I personally feel JavaScript is grossly misused today though, I feel your pain. any example websites?

>>13232 For me the hide post/image button often does nothing. But then again I have a lot disabled so I am not too surprised.
