Paul Lockhart wrote a great book called Measurement, about this and similar questions. I highly recommend it if you're interested in the topic.

I almost never close tabs. Maybe once or twice a year I close them all at once, but until then, the number just keeps growing and growing. Currently there are 2700 tabs open in my Firefox on Android. It still works relatively well. The only problem I notice is when I type in an address, it doesn't show the list of matching open tabs and history items. Inconvenient, but not critical. I should change my habits, yes.

I feel anxious looking at the multitude of windows. Do you get used to it?
