Opening a website in "developer mode" typically refers to accessing your browser's Developer Tools, which provide powerful features for inspecting, modifying, and debugging web pages. These tools are essential for web developers and curious users alike.
The quickest way to access these tools varies slightly depending on your browser, but there are standard menu options and keyboard shortcuts available in most modern browsers.
