Browser extensions are small programs with permissions. Review them like software, not wallpaper. Practical checks and official references.

Browser extensions are small programs with permissions. Review them like software, not wallpaper.

This guide expands the Facebook post into a practical workflow for beginners, home-lab users, and small-business owners who want to understand the trade-offs before changing a working system.

What this guide covers

  • Review browser extension permissions
  • Publisher, permissions, need.
  • Installed — What is running?
  • Permissions — Read + change
  • Still needed? — Update + remove

Why it matters

The goal is not to memorize a product name or copy a command blindly. It is to understand what the change affects, verify it against an official reference, test it on spare hardware or a virtual machine when possible, and keep a rollback path.

A practical walkthrough

Use the supported update path

Check installed extensions, who publishes each one, what it can read or change, when it was last updated, and whether you still need it. A permission to “read and change all your data on all websites” is broad; a permission limited to one site is narrower.

Check the assumptions

Use browser-neutral steps unless you have verified the current interface: open the extensions page, inspect details/permissions, and remove what you do not use. Check the publisher and the store listing, but do not assume store approval guarantees safety.

Use the supported update path

Remove extensions you do not recognize. Check whether the extension can read page content or only click. Prefer fewer extensions. After an update, recheck permissions; they can change. If an extension is abandoned, replace it or remove it. Review after browser updates. Use the browser's extension manager. Use the browser's extension manager.

Your turn

Which extension would you remove today?

What to verify

  • Use the official documentation for the exact version you run.
  • Test on a spare device or virtual machine before changing a working system.
  • Keep a backup and a rollback path.
  • Record what changed and how you verified it.

Common mistakes

  • Changing more than one thing at a time.
  • Skipping the official documentation for your version.
  • Assuming a warning means you should delete or reset data.
  • Not recording what you changed or how you verified it.

Quick checklist
