Tab Sense

Tab Sense is a privacy-conscious tab management extension that helps you clean up duplicate tabs and organize ungrouped tabs by topic using an AI provider of your choice.

Key features:

• Close duplicate tabs in the current window with one click.
• Always protect pinned tabs from automatic closure.
• Keep the active duplicate tab, or the leftmost one when no duplicate is active.
• Organize ungrouped, unpinned tabs into meaningful topic-based groups with AI.
• Reuse suitable existing tab groups before creating new ones.
• Support OpenAI, Anthropic, Google Gemini, and OpenAI-compatible APIs.
• Configure custom API endpoints, including local AI services.
• Create and switch between multiple AI provider profiles.
• Load available models and test a selected model before using it.
• Optionally remove duplicate tabs before AI grouping.
• Undo the most recent duplicate cleanup, AI grouping, or ungroup-all operation.
• Remove all tabs from their groups in the current window.
• Use keyboard shortcuts for quick access.
• Follow a built-in guided tour when using the extension for the first time.
• Use the interface in English or Simplified Chinese.

• Alt+Shift+D: Close duplicate tabs
• Alt+Shift+G: Group tabs with AI

When you start AI grouping, Tab Sense sends the selected provider limited tab metadata: tab titles and URLs with query parameters and fragments removed. It does not send page contents, cookies, form data, or browsing history outside the tabs being organized.

Tab Sense contains no advertising, analytics, tracking, or remotely hosted code. Your information is not sent to or collected by the extension author.

Requires Firefox 142 or later on desktop. Firefox for Android is not currently supported because it does not provide the tab-group extension APIs required by Tab Sense.
