You install an extension to tidy one website. Months later it is still running while you use webmail, open documents and manage other accounts. The useful question is whether its access still matches its job.
Start with the task
Write down what the extension does for you. A tool used on one site deserves a different access decision from a tool you deliberately use throughout the browser. The name, icon and star rating do not explain its permissions.
In Chrome, extension settings can offer access on click, on particular sites or on all sites. Available controls depend on the extension. Read the permission description before granting access; permission to read or change website data can be broad.
Try the narrower setting
Choose a specific site or access on click where that fits the task. Then test the feature on an ordinary page without sensitive information. If it stops working, find out which permission is missing before restoring everything at once.
An extension that needs broad access is not automatically malicious. It does require a stronger reason to trust its developer and to keep it installed.
Review what remains
Remove extensions you no longer use. Check the list in every browser profile, since your work and personal profiles may differ. After adding a new extension, put a reminder in your own calendar to review it once the initial experiment is over. A smaller, understood collection is easier to maintain than a drawer full of forgotten tools.
