The security of Chrome extensions can be guaranteed in four steps: 1. Priority is given to the official store to select high-rated, many comments, and trustworthy extensions from the official store; 2. Review the rationality of permissions during installation, such as ad blocking plug-ins should not require access to the camera; 3. Pay attention to abnormal behaviors, such as advertisement pop-ups, homepage tampered with, or browser slowing down, and check suspicious extensions in time; 4. Reducing risks requires streamlining installation, regular check for updates and permissions, enabling the "minimum permission" mode, and recommending the use of a privacy protection tool with good community evaluation. Staying alert and regular maintenance is key.

The security of Chrome extensions depends on their origin, permission requirements, and the developer's intentions. While many extensions are safe and useful, there are also many potential risks.

1. Viewing the source and rating is the first step

The number of expansions in the Google Chrome online app store is huge and the quality is uneven. The most basic point is: don't install unidentified extensions .

• Check the user ratings and comments before installing. A high rating of a large number of real reviews usually means that this extension is more reliable.
• It is also important to view developer information. A well-known company or developer with other popular products is usually more trustworthy.
• If a function looks "too easy to use" or "too powerful", such as being able to bypass paywalls, automatically view video duration, etc., then you should be more careful.

2. Pay attention to whether the permissions it requests are reasonable

When you install an extension, the browser prompts it for what permissions it needs. This is an important part of judging security.

For example:

• A simple ad blocking plugin that has problems if you require access to your history, camera, or even file system.
• It is relatively reasonable for a password manager to require access to form data and information from multiple websites.

You can do this:

• After installation, click the extension icon on the right side of the address bar → select "Manage extensions" → view all permissions for the extension application.
• If you find that an installed extension has too high permissions, you can consider uninstalling or looking for a replacement.

3. Some malicious behaviors are not easily noticed

Some extensions do not expose the problem immediately, but instead collect data quietly or implant ad scripts.

Common phenomena include:

• A strange ad pops up when browsing the web
• Home page or search engine is modified to a URL you are not familiar with
• The browser slows down, even stutters or crashes

If you encounter these situations, it is recommended to check out recently installed extensions, especially those you don't remember very much for use.

4. How to reduce the risk of using extensions

In fact, just pay attention to a few details, you can avoid getting stuck to the pit to a large extent:

• Try to install only the extensions you really need, and uninstall them in time if you don't need them.
• Check for any extensions regularly to see if there are any update log exceptions or permission changes
• Use the "minimum permission principle" - for example, some extensions can be enabled only on specific websites
• You can consider using "privacy protection" extensions, such as uBlock Origin (ad blocking), Privacy Badger (anti-tracking), etc. These tools are generally better evaluated by the community.

Basically that's it. Chrome extensions are indeed convenient, but they are also easy to become an entrance to security risks. Staying alert, cleaning up regularly, and paying attention to authority is the long-term solution.
