HI! I would like some clarity on the support of Microsoft Edge in the SWT Browser. I am creating an RCP application that makes use of the SWT Browser. On Windows, we all know that IE is the default browser used by the SWT Browser. IE is no longer a modern browser, and Edge is the future for Microsoft. The URL we use within our SWT Browser instance is to a Node.JS server running a JS app. The JS app is a very modern app which makes use of ECMAScript 6. IE as I understand it does not support ECMAScript 6 so we often run into issues when ES6 features are used. However, when we take the same URL/app and run it with Edge, Firefox, or Chrome outside of Eclipse, all works perfectly.
By chance, we found that if we set this property in eclipse.ini, Edge will be used:


We verify that Edge is used by opening a browser in Eclipse and entering We cannot find documentation on this option, nor can we find any documentation regarding Eclipse + Edge. However, even though Edge appears to be used by Eclipse with the aforementioned property, we unfortunately find that the issues we see in IE with our URL/app also appears with Edge in Eclipse. Again, it works perfectly in Edge outside of Eclipse.

Having said all this, we'd like to know if there is a statement by Eclipse regarding Edge. Furthermore, we'd like to know where the work was performed to support IEVersion=12001. If I set IEVersion=13001 the default IE is used...given this, it seems clear to us that someone has added support for Edge, be it preliminary, with the specific value of 12001. Finally, the ideas [1] to support Chromium in SWT Browser sound like a great idea! We'd ultimately like to use Chromium since it should play well on all OSs......we are only looking at Edge as a stop gap until such time as Chromium is supported by the SWT Browser.

I suspect you're hitting the IE compat view detection. See the following links for details:

We have to use an HTML5 doctype and add a `<meta http-equiv="X-UA-Compatible" content="IE=edge">` element to the `<head>` section to instruct IE to "display content in the highest mode available."
