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.
