How to judge an extension before you install it
- Permissions: If it wants to read and change data on all sites, it needs a very good reason.
- Recent updates: Not updated in a year is a risk.
- Developer and privacy policy: Look for a real company and a clear policy.
- Reviews and installs: Useful signal, not proof, when combined with the checks above.
Extensions people actually keep
- Writing and grammar: Grammarly, polish emails and posts as you type.
- Summarizers: Merlin, Monica, Sider, turn long pages and videos into short briefs.
- Research: Perplexity and Gemini extensions, cited answers without opening ten tabs.
- Reading: Use one summarizer, not five. Pin only what you use daily.
A setup that works
Install one summarizer, one writing helper, and one research tool. Pin only the ones you use daily. Turn off the rest. If Chrome feels slower after installing an extension, remove it. No feature is worth a slow browser. Review extensions once a month and delete anything you have not used in 30 days.
Privacy checklist: Prefer extensions that work only when you ask them to. Avoid extensions that inject ads or change search results. If a free extension is vague about how it makes money, treat that as a warning.
