Often when someone (usually a professor) is sharing their screen I see that their browser has so many tabs open that the descriptions are lost: That was my best impersonation as a Firefox user. Chrome will let you go a lot further (like ~113 tabs) before starting to provide a dropdown to show you the list of open tabs: Besides the obvious fact that this makes it hard to find a tab you’re looking for, you also waste computer memory and add to your cognitive load while you’re working.
