User reviews

New Tab Suspender is appreciated for effectively reducing memory usage by suspending inactive tabs, supporting heavy tab workloads, and running reliably over time. However, users frequently report issues with suspension timing settings not applying correctly and whitelist features being unreliable or hard to manage. The lack of backup or sync options for settings and whitelist is a significant drawback. Additionally, the add-on can suspend tabs with active forms causing data loss, and it lacks clear documentation to guide users through its options.

Pros

Effectively suspends inactive tabs, reducing memory usage especially beneficial for low RAM systems.
Allows managing a large number of tabs (close to a hundred) with automatic suspension in the background.
Simple and functional, serving its basic purpose well compared to other extensions.
Offers some level of customization like setting suspension time and whitelisting tabs (though with some issues).
Has been reliable and used by users for over a year with consistent performance.

Cons

Suspend time setting does not always work correctly; users report it defaults to 5 minutes regardless of their configuration.
The "Don't suspend this tab" or whitelist feature is problematic – either not working properly or difficult to manage/identify which tabs are whitelisted.
No easy way to backup, export, or sync settings and whitelist across installations causing frustration when reinstalling browsers or OS.
It can suspend tabs with active forms leading to loss of typed information if user is not careful.
Lacks clear documentation or guidance on where to find options, configure settings, or how features work, making it confusing for new users.
