If you’re looking for a way to limit open tabs in Safari on macOS, you’ll quickly notice that Safari doesn’t offer a built-in tab limit.
You can open unlimited tabs, which often leads to tab overload, loss of focus, and cluttered workflows.
Why Safari Doesn’t Let You Limit Open Tabs
Safari is designed to be flexible, but that flexibility comes at a cost. By default, there’s no restriction on how many tabs you can open, which makes it easy to postpone decisions and keep everything “just in case.”
Over time, this creates cognitive overload rather than helping productivity.
Do Safari Tab Groups Solve Tab Overload?
Tab Groups help organize tabs, but they don’t actually prevent overload. You can still open unlimited tabs inside each group, which means the core problem remains: there’s no guardrail.
Organization is not the same as limitation.
A Simple Tab Limit Extension for Safari on macOS
Instead of managing tabs after the chaos starts, a better approach is to stop the chaos before it happens.
A tab limit creates a clear boundary: once you reach a certain number of tabs, Safari simply won’t open more.
How to Stop Opening Too Many Tabs in Safari
The most effective way to stop opening too many tabs isn’t relying on willpower — it’s adding a hard constraint.
When new tabs are blocked after a limit, you’re forced to either close existing ones or finish what you started.
Is There a Safari Extension to Limit Tabs?
Yes. TabCap is a Safari extension for macOS that lets you set a maximum number of open tabs. Once the limit is reached, Safari won’t open new tabs until you close existing ones.
