What extensions or tools do you use to keep your Chrome tabs organized?

I never tried any tab organizer extension. Thanks for sharing, I'll check Marble.

I just use "Close all tabs," gives me a freshstart.

Yes, I also use Marble for organizing the tabs in Chrome. My Chrome tab usage involves having 40-50 tabs open at a time, and without this extension, it feels like I'm lost in Chrome tabs.

Marble - Group Tabs Automatically.

Workona Spaces and Tab Manager

Tab Groups Extension

Project White Rabbit is great for this! (link on my profile) It's a desktop app that syncs with your browser to automatically group and clean up your tabs, and saves them to the app where you can open / close. It also integrates them with a note editor so you can add context to all your web content. disclosure - i'm an investor + advisor, as well as an active user!
