User Agent: Mozilla/5.0 (Macintosh; Intel Mac OS X 10.8; rv:32.0) Gecko/20100101 Firefox/32.0 Build ID: 20140917194002 Steps to reproduce: create a box using :before on <botton type="button"> see http://jsbin.com/noyaji/3 Actual results: the :before generated box is visible but does not capture mouse events. text below the layer could be selected, other elements clicked. Expected results: clicking on the :before generated box should have triggered a click on the <button>, text below the generated box should not be selectable

I have also tested this in Firefox 35.0a1 (2014-10-02) with the same result. I have however gotten reports that the problem might not exist on Windows. Not sure what to make of this, I only tested on Mac OS 10.8.5.

I can confirm this on OS X 10.9.5 with Firefox Nightly from today (v35.0a 2014-10-02).

This is basically a dup of bug 843003

(In reply to j.j. (mostly inactive) from comment #3) > This is basically a dup of bug 843003 ... basically not, because it works indeed on Windows Mozilla/5.0 (Windows NT 5.1; rv:32.0) Gecko/20100101 Firefox/32.0
