Smart Tab Merge – Organize Multiple Windows with Ease

[Akash_gite]

 Problem Statement:

Modern users often manage dozens of tabs spread across multiple Firefox windows. This creates clutter, makes it difficult to locate tabs, and affects productivity. There’s currently no built-in feature to efficiently merge and organize tabs across windows.

---

Proposed Solution: Smart Tab Merge

Introduce a feature called "Smart Tab Merge" that allows users to:

• Merge multiple open windows into a single window

• Group tabs based on relevance, tasks, or user preference

• Create named tab groups (e.g., "Work", "Shopping", "Research")

• Collapse/expand tab groups as needed

• Easily switch between tab groups using a dropdown or sidebar

---

 Key Features:

• Merge multiple windows into one with drag-and-drop or a “Merge Windows” button

• Create and name tab groups for easy navigation

• Navigate between tab groups using a left sidebar or dropdown on the tab bar

• Optional: AI-assisted grouping suggestions based on tab content or domains

---

Benefits:

• Improves tab and window organization

• Increases productivity during research or multitasking

• Reduces memory usage by limiting the number of open windows

• Makes Firefox more user-friendly and workspace-oriented

---

 Inspiration:

Inspired by tab grouping in Chrome and tools like OneTab — but with advanced merge, group, and organize capabilities built directly into the browser.

treestyle tab is a great and very advanced addon for tab management, but it is also not possible to merge windows together in one.

1.) Especially when you PC (windows) crashes an wehener the recovery of sessions is needed someone can get lost to find the last tab... sometimes a session with all windows will be recovered by treestyle tab, but with a lot of doubles after restart of Firefox.
This is why i try to merge my windows from time to time in one window manually.

2.) Sometimes external links from windows programms open up Firefox in a new windows (especially if you have different profiles).

Would be great to merge all windows in one with one or two clicks...
