Enable Development Mode

Although you can view and edit Visualforce page definitions on the Visualforce Pages page in Setup, enabling Visualforce development mode is the best way to build Visualforce pages.

Required Editions

Available in: Salesforce Classic and Lightning Experience
Available in: Contact Manager, Group, Professional, Enterprise, Performance, Unlimited, and Developer Editions
User Permissions Needed
To enable development mode: Customize Application

Development mode provides you with:

  • A special development footer on every Visualforce page that includes the page’s view state, any associated controller, a link to the component reference documentation, and a page markup editor that offers highlighting, find-replace functionality, and auto-suggest for component tag and attribute names.
  • The ability to define new Visualforce pages just by entering a unique URL.
  • Error messages that include more detailed stack traces than what standard users receive.
  1. From your personal settings, enter Advanced User Details in the Quick Find box, then select Advanced User Details.
    No results? Enter Personal Information in the Quick Find box, then select Personal Information.
  2. Click Edit.
  3. Select the Development Mode checkbox.
  4. Optionally, select the Show View State in Development Mode checkbox to enable the View State tab on the development footer. This tab is useful for monitoring the performance of your Visualforce pages.
  5. Click Save.
