## Description

**UnloadTabs** is a powerful Chrome extension designed to help users manage browser tabs efficiently by unloading inactive tabs to free system resources and prevent them from loading unintentionally. It integrates context menu entries to unload the current tab or all but the current tab, along with keyboard shortcuts to jump between loaded tabs. The extension is compatible with popular add-ons like Tree Style Tab and Container Tabs, maintaining tab organization while optimizing performance.

UnloadTabs visually distinguishes unloaded tabs by graying them out (with manual setup), ensures unloaded tabs remain in correct containers, and provides a clean uninstall feature that leaves no residual tabs closed. While the extension handles tab unloading seamlessly, some Firefox-specific bugs related to tab icons and loading status exist, which are being addressed by Mozilla. Users are encouraged to report other issues via the developer's GitHub repository. Permissions are limited to displaying error notifications and accessing browser tabs, ensuring transparency and privacy.

## Review summary

UnloadTabs helps reduce browser resource usage by unloading pages while keeping tabs visible for quick reloads. It supports hotkeys to unload the current or other tabs and is praised for its simple, exact functionality. However, users note missing timing control (no unload-delay), per-tab only unloading (no bulk/window options), occasional stability and focus issues, and a missing default action when no loaded tab is available. Overall, it’s handy for managing many tabs and low RAM, with some reliability caveats.

### Pros

- Frees up memory and CPU by unloading the page while keeping the tab in the tab list, helping with many tabs or limited RAM.
- Hotkeys allow unloading the current tab and unloading other tabs (except the current) for quick control.
- Simple, focused functionality that does exactly what users want; works as advertised.
- Unloaded tabs stay visible in the list for easy reloading.

### Cons

- No option to set a delay before unload, limiting timing control.
- Only per-tab unload; no batch/bulk unload or window-wide unload support.
- Stability issues reported (some reviews mention features breaking or browser problems).
- Unloading may cause focus issues; Firefox might not reliably focus unloaded tabs afterward.
- Edge-case behavior: when there is no loaded tab to switch to, the extension lacks a default action such as opening a new tab.
