Context menu contains un-needed items

[SuborbitalPigeon]

In the WebView widget, I think the default context menu is used. This includes 'Stop', 'Reload' and 'Inspect Element'. I suggest it would be better if they're removed, leaving just 'Back' and 'Forward'.

Here's an example of how to fix this.

Note the "Open Link in New Window" and "Download Linked File" context menu items are both actually broken.
