I keep open 200 and more tabs, especially when I can't finish a job before I start or continue another one. It's a matter of efficiency - closing a group of tabs found after painful and time-consuming research is unreasonable IMO. To find a specific tab after a day or two I use the tabFX Firefox extension. It allows searching for the tab containing keywords in the title/URL or tabs similar to the selected one. Also allows closing tabs directly from the search result list. Extremely useful.
