It’s late at night and you’re stalking an old friend’s Instagram. It’s all going well, until you accidentally “like” a photo from 42 weeks ago. I’ve been there; many of us have been there. The next time this happens to you, here’s a tip, recently shared by a Twitter user, in case of extreme, mortifying emergency.

Android: Sometimes you want to watch a video on YouTube and not have it show up in your history. For those moments when you need to go undercover, YouTube recently added an Incognito mode that makes it easier to watch videos without leaving a trace.

Chrome: When you want to visit a website without being tracked, Incognito mode can log you out and prevent most tracking. However, you lose your extensions by default. Fortunately, you can enable them.
