Microsoft Edge

Tested version 40.15063.0.0 (64-bit) with the following settings:

Microsoft Edge
			^(.*)(?: and \d+ more pages)? ‎- Microsoft Edge

There are several issues that make the browser hard to detect:

  • Main window is hosted inside ApplicationFrameHost.exe, which hosts other windows such as Settings (i.e. Control Panel) with the same ApplicationFrameWindow class.
  • The process runs within system directories, which we ignore.
  • Tabs are laid out differently than other browsers.
  • Window title relies on the system language and contains an invisible left-to-right mark right before - Microsoft Edge.

Tested version 1.10.867.48. Doesn't expose UIA tree. URL and tabs not detectable.

Tested version 1.14.1077.60. While the window itself is available in the UIA tree, its descendants are not.

Tested version 2.11.1811.52. The URL bar and the tabs are now available, but:

  • Everything (including the actual document) is wrapped within an extra document control, which we ignore for performance.
  • Tab controls aren't marked as such.
  • The tree is overall quite messy.

Tested version 5.0.2497.38. Not much has changed.
