I feel like with a bit more improvements to Firefox Snooze Tab [1] and Container Tab [2] extensions the need to have tons of tabs open could be solved.

What if it's easy to easily have multiple "Research containers"?

Container tab allows you to hide all tabs related to a particular container, so I feel like you can easily improve your workflow.

What about combining that functionality with snooze tab extension? But instead of snoozing individual tabs, snooze a container.
