A browser can become a collection of unfinished intentions. Some tabs belong to a task in progress; others are references or things you hoped to read.

Separate those purposes in a way that fits your browser. Save a useful reference with a descriptive name, and keep active work grouped clearly enough to return to.

Close what no longer has a job. The aim is not a particular tab count, but a workspace in which finding the next step takes less effort.

Imagine a practical setting.

Imagine saving a short reading list before closing a group of research tabs. Each reference can keep its purpose without occupying the active workspace.

Before the next experiment.

Try the method on one real task before making it universal. The exception you discover may be the most useful part of the experiment.
A few starting points
  1. Distinguish active work from saved references.
  2. Use descriptive bookmark names.
  3. Close a tab whose purpose has ended.
