Where can Visualforce pages be edited within Salesforce?

Visualforce pages can be edited within Salesforce using the Setup menu, which provides a dedicated interface for managing and customizing various Salesforce components, including Visualforce pages. By navigating to the Setup menu, users can access the "Visualforce Pages" section, where they can create, edit, and manage their Visualforce pages directly within the Salesforce environment.

This approach allows users to leverage the built-in tools and frameworks provided by Salesforce, ensuring that they are working within the established security and data governance frameworks of the platform. Editing through the Setup menu is particularly beneficial for those who prefer a graphical interface without needing to rely on external tools.

Other options like the Salesforce mobile app or the Dev Console do not provide robust functionalities for editing Visualforce pages. While the Force.com IDE can be used for development purposes, it functions as an external integrated development environment compared to the more accessible and integrated method provided through the Setup menu.
