Why Use Incognito/Private Browsing Mode for Testing Websites?
- Purpose and Benefits:
- Incognito/Private Browsing Mode lets you surf the internet without saving your history, cookies, or other data. This is helpful for testing websites because it allows you to see the site as if you were a new visitor. It ensures that old data or saved settings don’t affect what you see.
- Using this mode helps you spot problems that might not show up otherwise, like outdated content or issues caused by stored data.
- Limitations:
- Incognito/Private Browsing Mode hides your browsing from being saved on your device but doesn’t hide it from the websites you visit, your employer, or your internet service provider.
