I am happy to report that an experiment with not closing tabs in Google Chrome showed that approach is not sustainable. The benefit of not closing tabs is having your context always fresh, but after 1,200+ tabs, Chrome became sluggish overall, with UI slowdowns for many operations, such as opening a tab, moving a tab, or switching to a tab. Additionally, starting Chrome took a significant amount of time, about 10 seconds. Furthermore, the benefits of keeping the context diminished after a certain threshold, because opening tabs consumed RAM, and you cannot actually review more than 50 tabs at a time.
