Change Brackets' default browser

By default Live preview in Brackets is set to Google Chrome Browser. To change this
- Go to Debug
- Open Preferences file and
- change this line from “livedev.multibrowser”: false to “livedev.multibrowser”: true.

Close the Brackets App and open it again.

Clicking on  “Live Preview” should now start in your default browser (like Safari or any other browser).
