Affecting Support for Event.srcElement has been added

Published: | Categories: DOM


Firefox now supports the non-standard srcElement property on the Event interface for a better cross-browser compatibility. Firefox Nightly has already added the support since the version 60. It’s the standard target property’s alias originated from Internet Explorer, which has been implemented in all other browsers by now.

Mozilla engineers are concerned about the possibility of broken sites if it’s misused for browser detection targeting Firefox. Make sure your site is not the case.
