Tab groups were supposed to fix the tab problem. Chrome added them in 2020. Edge copied them. Users celebrated. Finally, a way to organize the chaos.
But tab groups do not fix anything. They hide it. They take 30 tabs and compress them into colored blobs so you stop seeing the mess. The tabs are still there. They still eat RAM. They still break your focus. You just stopped looking at them.
What Tab Groups Actually Do
Tab groups let you drag tabs into color-coded folders. You can name them, collapse them, and expand them. A group of 10 tabs becomes a single colored bar with a label.
Your tab bar goes from a crowded strip of unreadable favicons to a neat row of colored blocks. It looks better. You feel in control.
But nothing changed under the hood. Those 10 tabs are still running as 10 separate processes. They still consume the same RAM. They still execute JavaScript in the background. They still send network requests. The only difference is that you cannot see their titles anymore.
Three Ways Tab Groups Make Things Worse
1. They Encourage Hoarding
Before tab groups, 20 tabs looked like a mess. You felt pressure to close some. The visual clutter was uncomfortable. That discomfort was useful feedback.
Tab groups remove that feedback. You can fit 40 tabs into four collapsed groups and your bar looks tidy. The pressure disappears. You stop closing tabs because you no longer feel like you have too many. Your tab count doubles without you noticing.
I tracked this for two weeks. With tab groups, my average tab count went from 18 to 34. The groups made me feel organized, so I stopped organizing. I just kept opening.
2. They Add Manual Work
Every new tab needs a decision. Which group does it belong in? Is this Hacker News thread "Research" or "Reading"? Is this GitHub issue "Work" or "Later"? You spend time sorting instead of working.
And the sorting is never permanent. Groups drift. A "Research" group started on Monday becomes a mix of research, shopping, and random articles by Wednesday. You re-sort. You re-name. You re-color. You are now a tab librarian instead of a worker.
I spent 15 to 20 minutes per day just managing my groups. Dragging tabs. Renaming groups. Collapsing and expanding. That is over an hour a week spent on tab cosmetics.
3. They Do Not Reduce RAM or CPU
This is the dealbreaker. Tab groups are a UI feature, not a system feature. Chrome does not run grouped tabs more efficiently. A tab in a group uses the same memory as a tab outside a group. A collapsed group does not free RAM. A hidden tab does not stop executing JavaScript.
I tested this with Chrome's built-in Task Manager. A group of 12 tabs used 1.8GB of RAM. I collapsed the group. RAM usage: still 1.8GB. I expanded the group. RAM usage: still 1.8GB. The group changed nothing. It just changed what I could see.
If your browser is slow, tab groups will not fix it. If your fan is spinning, tab groups will not stop it. If your battery is draining, tab groups will not save it. They are paint on a crumbling wall.
Head-to-Head: Tab Groups vs Actually Reducing Tabs
| Metric | 30 Tabs in 4 Groups | 5 Tabs, No Groups |
|---|---|---|
| RAM usage | 3.2 GB | 0.8 GB |
| CPU load | High (30 processes running) | Low (5 processes running) |
| Context switches | Frequent (hard to find the right tab) | Minimal (every tab is visible) |
| Tab management time | 15-20 min/day sorting | 2-3 min/day closing |
| Focus recovery | 23 min per switch (Gloria Mark) | Minimal (fewer switches) |
| Visual clutter | Low (collapsed groups look clean) | Low (only 5 tabs) |
| Actual productivity | Lower (more tabs = more distraction) | Higher (fewer tabs = deeper focus) |
The only metric where groups win is visual clutter. And they win it by lying to you. The 5-tab setup actually has less clutter because it has less stuff. The group setup hides the stuff so you think there is less. Your eyes are fooled. Your computer is not.
The One Time Tab Groups Actually Help
Tab groups have one valid use case: temporary active sessions with 6 to 12 tabs.
You are writing a report. You need 8 sources open right now. You group them so they do not get lost among your other tabs. You finish the report. You close the entire group. Session over. The group served as a temporary container for a specific task.
This works because the group is short-lived. It exists for one task and dies with it. The problem starts when groups become permanent. A "Read Later" group that lives for three weeks is not a group. It is a badly designed bookmark system that eats 2GB of RAM.
What to Do Instead
If you have 30 tabs open, you do not need better groups. You need fewer tabs. And the way to get fewer tabs is to stop treating every link like a commitment.
Most of your tabs are not workspaces. They are glances. You opened a link to verify a source, check a reference, or read a headline. You did not need a new tab for that. You needed a preview.
Use GoPeek to preview links instead of opening them. Hold Shift, hover the link, and the page opens in a floating window. Read what you need. Close it. No tab. No group. No RAM.
For the few tabs you actually need to keep, use bookmarks. Bookmarks are deliberate. They are permanent storage for things you will revisit. Tabs are temporary workspaces. If a tab is not part of your current task, it should be a bookmark or a preview. Not a tab. Not a group.
The Bottom Line
Tab groups are a cosmetic fix for a systemic problem. They make you feel organized while your browser chokes on 30 running processes. They hide the clutter so you stop cleaning it. They turn you into a librarian instead of a worker.
The real fix is simpler and harder: open fewer tabs. Preview links instead of tabbing them. Bookmark references instead of hoarding them. Close tabs when you are done. Your browser will run faster. Your focus will last longer. And you will never need to color-code your chaos again.
