User reviews

The Marvellous Suspender is praised widely for efficiently managing memory by suspending unused tabs, especially beneficial for users with many open tabs. However, it faces critical issues due to incompatibility with recent Chrome updates and Google's policy changes, leading to its disabling. Users express a strong desire for the developer to update the extension to Manifest V3. Despite functional setbacks, some users find ways to re-enable or locally install versions, emphasizing its importance in managing browser performance.

Pros

Effectively suspends unused tabs to save RAM and improve browser performance.
Highly appreciated by users for handling many open tabs and memory management.
Simple to use and reliable in suspending tabs as commanded.
Some users have workaround solutions to keep using it even after Chrome disables it.
Widely regarded as one of the best Chrome extensions for tab management and memory saving.

Cons

Currently incompatible with the latest Chrome versions due to Manifest V2 being deprecated without Manifest V3 support.
Extension disabled or removed by Chrome updates, causing users to lose functionality.
Lack of timely updates to comply with Google's new extension policies.
Some features, such as screen capturing before suspending, do not work as expected.
Risk of tab disruption or duplication when using Chrome's new memory management alongside the extension.

What a shame that Google has destroyed this awesome extension.. Really hoping these guys can get it working on the next version of Chrome because Chromes native tab suspension system "Memory Saver", is absolute trash in comparison. I see that there is a Marvellous Suspender v3 Beta.. I don't know if you can link stuff in reviews, so just type what I wrote "Marvellous Suspender v3 Beta" into Google Search and you'll see how to get it. Hope this helps some people.

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.

The Marvellous Suspender requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood measures the probability that a Chrome extension may turn malicious. This is determined by the publisher and the Chrome extension reputation on Chrome Web Store, the amount of time the Chrome extension has been around, and other signals about the Chrome extension. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Chrome extension.

The Marvellous Suspender has earned a fairly good reputation and likely can be trusted.
