## Review summary

Users widely praise the add-on for dramatically reducing memory/CPU usage by suspending inactive tabs and for reliable core features (timer, whitelist, ignore) that preserve tab context and reactivation. It works well on low-RAM systems and is generally simple to configure. However, multiple reviews call out UI discoverability issues and lack of basic setup instructions, as well as problems with per-tab exception handling and the absence of export/import or browser-sync for backing up settings.

### Pros

- Substantially reduces CPU and memory usage by suspending inactive tabs.
- Core features like timer control, whitelist, and ignore lists work reliably and are easy to configure.
- Automatically suspends inactive tabs while preserving context, and reactivates on click from where you left off.
- Very effective on low-RAM systems, enabling suspending many tabs without bogging down the browser.
- Simple and clear to control/configure once you understand the basic controls.

### Cons

- UI/controls are not obvious to find and basic setup information or instructions are missing, making initial use confusing.
- Per-tab 'Don't suspend this tab' option is hard to see/manage and is not reliably working for all tabs.
- No export/import, backup, or browser-synced settings, making it hard to transfer or safeguard configurations.
