I've only been using this service (it's a paid service) a while, but I'm seriously impressed by it.
Partizion is a plugin that allows me to condense down my myriad of tabs into workspaces (think home, work, plans, hobbies), and then further refine and distill that down to collections (so maybe email, social media, research, etc). The workspaces allow me to shift between what I'm working on quickly, while collections allow me to open and close a bundle of tabs with as little as a click.
For me, this has become a huge productivity and performance booster.
