User reviews

Tab Suspender is praised for its lightweight design and effective memory savings by suspending inactive tabs, with users appreciating its simplicity and reliability over time. However, common issues include lack of whitelist support, inability to exclude media-playing tabs, no auto-suspend timeout, and limited manual tab suspension control. Some users report that suspending tabs can inadvertently affect more tabs than intended, reducing accessibility. Overall, it fulfills its primary purpose but could benefit from enhanced customization and control features.

This extension would be perfect if it had an option to not suspend tabs that are playing media

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.

Tab Suspender requires a few sensitive permissions. Exercise caution before installing.
