Thread:VisualEditor/Feedback/IE ?/reply

Internet Explorer support is tracked from bug 50085. There are a number of relatively-minor issues, and one complete show-stopper: bug 49187 - Internet Explorer's security model means that the cross-server requests used to save the page don't work, so users can never save their work. We plan to build a work-around this model, but for now it means VisualEditor is unusable on Internet Explorer.

Note that our intent is to provide support for IE9 and above; IE8 fails to support many of the key technologies used in VisualEditor, so supporting it would require us to create a forked version of VisualEditor just for IE8, which is not something we can justify.
