Browser extensions add features such as password management, accessibility support, translation and note-taking. Because extensions can interact with websites and browsing data, choose them carefully.
What extensions may access
Depending on permissions, extensions may read or change website data, manage downloads, access tabs or communicate with other apps. Permissions should be proportionate to the feature offered.
Assess an extension
- Check the publisher and official website.
- Review permissions before installing.
- Look at update history and support details.
- Read recent reviews.
- Check privacy and data-sharing practices.
- Avoid tools demanding unrelated access.
Reduce risk
Install only extensions you need, remove unused tools and review permissions after updates. Keep your browser current and follow workplace policies.
If an extension behaves strangely
Disable or remove it, review other recent installations and check browser settings for unexpected changes. If sensitive accounts may be affected, review account activity from a trusted device.
FAQs
Can extensions read passwords?
Access depends on permissions and browser controls. Treat broad website-data access as sensitive.
Can extensions slow a browser?
Yes. Many active extensions can use memory and CPU; remove those you do not need.
