自动休眠闲置标签页，释放内存、让浏览器更流畅。达到设定闲置时长后，扩展会用 Firefox 原生机制卸载页面，只剩一个轻量休眠页，点击"恢复"（或按空格、移动鼠标）即可随时回到原网页。

可自定义休眠等待时长、设置域名白名单（不受休眠影响）
支持"休眠其他所有标签页"，快捷键 Ctrl+Alt+F；也可手动休眠当前标签页
Split View 分屏下的两个标签页会同时保活，不会误休眠
休眠页可个性化：背景/按钮颜色、标题前缀、是否启用鼠标移动即恢复
多语言支持，界面简洁易用


Automatically hibernate idle tabs with Firefox's native discard mechanism to free up memory and keep browsing smooth. Once a tab is idle past the threshold, it collapses into a lightweight sleep page; click "Resume" (or press Space / move the mouse) to jump right back.

Configurable idle threshold and a domain whitelist (exempted from hibernation)
"Hibernate all other tabs" action with a Ctrl+Alt+F shortcut, or hibernate the current tab on demand
Tabs shown together in Split View are kept alive together — never wrongly frozen
Customize the sleep page: background / button color, title prefix, and toggle restore-on-mouse-move
Multi-language safe and lightweight
