User reviews
Pros
- Allows customization of suspension time, including longer durations like two hours, unlike some other extensions.
- Lightweight and efficient, uses minimal permissions.
- Simple and easy to use with straightforward options.
- Effectively suspends tabs to reduce resource usage.
- Displays number of open tabs on the addon icon, although limited to 3 digits.
Cons
- Lacks a clear visual indicator or notification of suspended tabs; users want icons or tab text to be greyed out or show transparency.
- Does not allow manual suspension or unsuspension of tabs, being fully automated.
- Has performance issues when handling very large numbers of tabs (thousands), leading to sluggishness.
- Some users report increased memory usage after installing the extension.
- Tab icons do not change when a tab is suspended, causing confusion.

Extension safety
Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk
impact extension cannot do much harms, whereas a high risk impact extension can do a lot of
damage like stealing your password, bypassing your security settings, and accessing your
personal data. High risk impact extensions are not necessarily malicious. However, if they
do turn malicious, they can be very harmful.
Total Suspender requires a few sensitive permissions. Exercise caution before installing.
Risk impact analysis details
