It sounds like you're running into an early error. For instance:

> TypeError: undefined is not an object (evaluating 'this.modifierKeys.altKey')

This sounds like:

    WebInspector._updateModifierKeys = function(event)
    {
        var didChange = this.modifierKeys.altKey !== event.altKey || this.modifierKeys.metaKey !== event.metaKey || this.modifierKeys.shiftKey !== event.shiftKey;
        ...
    };

Somehow this code got called and either "this" or "this.modifierKeys" was undefined. That shouldn't happen, modifierKeys is initialized in WebInspector.contentLoaded.

This should be defined via Resizer.js.

- Are there earlier errors? The earliest error may give an indication as what is going on!
- Are ES6 classes supported in the browser showing the remote inspector?
- Maybe Symbol is not supported? Timothy Hatcher has a patch that monkey-patches that in to a degree:
Adding a window.Symbol to InspectorFrontendHostStub.js

I suspect it is window.Symbol issues.
