Do you mean overload to your senses? I always close most of my tabs. My policy is that if you don't bookmark, you don't care enough. Same goes for my local data

Do you mean overload to your senses? I always close most of my tabs. My policy is that if you don't bookmark, you don't care enough. Same goes for my local data. If I don't remember what's on my disk, or haven't backed it up periodically, I don't care about what's on it. If you mean about RAM usage: https://chromewebstore.google.com/detail/tab-suspender/fiabciakcmgepblmdkmemdbbkilneeeh https://chromewebstore.google.com/detail/tab-suspender/fiabc... is a good extension.
