Windows 10 complains "An app default was reset" when the default browser switches between Firefox and Nightly
Steps to reproduce: 1. Make sure KB3135173 is installed. 2. Install the release version of Firefox. 3. Install Nightly. 4. Options-General-Make default on Firefox. 5. Options-General-Make default on Nightly. Actual result: Toast will popup that says "An app default was reset". Expected result: No message should popup. The reason is probably because Firefox and Nightly share the same ProgIds (FirefoxHTML and FirefoxURL).
Another STR: 1. Make sure KB3135173 (or Anniversary Update) is installed. 2. Install the release version of Firefox. 3. Options-General-Make default on Firefox. 4. Install Nightly.
Now Windows 10 *silently* takes over the default browser!
Duping forward because the new bug got more attention.
