Page Manager by Domain per heysion

If you're like me and often have a huge number of tabs open—especially those opened from searches—you’ve probably had moments when you wanted to clean things up, only to find it's a hassle to close them one by one.

That’s when you need a tab management tool that organizes your tabs by website domain. It groups tabs based on top-level and second-level domains, and lets you close an entire group with one click, helping you quickly get your browser back under control.

Sounds useful, right? Exactly—that’s what this tool was made for.
