Extension summary

The Screen Curtain extension allows engineers, testers, educators, and students to temporarily obscure web technologies while using screen readers in order to simulate the experience of using such technologies without sight.

This is analogous to the Screen Curtain mode provided on iPhone and iPad devices when using VoiceOver to experience the same. This bookmarklet should be used in combination with JAWS or NVDA on Windows when testing the non-sighted experience of typical screen reader users.
