## Description

When you hover over a collapsed tab group and click a tab from the preview panel, Firefox normally expands the group. This add-on collapses it back automatically after a configurable delay.

Features:
• Enable / disable toggle
• Configurable collapse delay (100–1000 ms, default 300 ms)
• Works with Firefox's native horizontal tab groups
• Requires Firefox 140+

切換到群組內的分頁後，自動將該群組折疊，保持分頁列整潔。從 hover 預覽面板點選分頁後，Firefox 會自動展開群組，此擴充套件會在可設定的延遲後自動將其折疊回去。
