About this extension

New Tab Same Group is a Firefox extension that improves tab organization by automatically inserting new tabs into the same group as your current active tab — right after it, at the beginning, or at the end of the group, based on your preference.
This extension only works with native tab grouping v138+

🚀 Features

✅ Automatically groups new tabs with the active one
🎯 Choose where new tabs are inserted:
After active tab (default)
At the beginning of the current group
At the end of the current group
🧠 Smart tracking of the source tab to ensure consistent behavior
⌨️ Optional keyboard shortcut (Alt+Shift+T by default) to open a new tab in the standard Firefox way, without applying grouping logic. This can be toggled in the extension's options.
🖤 Fully supports Firefox's native tab groups
🔒 Zero tracking, zero external dependencies
🧩 Works perfectly with both vertical tab layouts and classic horizontal tabs

🛠 Requirements

Firefox 138 or higher
The browser’s native tab grouping system must be enabled

⚙️ How to Enable Tab Groups in Firefox

This extension works with both classic horizontal tabs and vertical tabs in the sidebar.

If you don’t see tab groups:

Open the sidebar via F1 or View → Sidebar → Tabs
Right-click on a tab and choose Move Tab to New Group

If tab grouping is missing entirely:

Go to about:config
Search for browser.tabs.grouping.enabled
If it exists, set it to true
Restart Firefox

🟣 Note: This extension only works with native tab grouping, not third-party tab managers.

Release notes for 1.6.4

🆕 New in version 1.6.4

• Improved reliability: source tab is now determined using a snapshot + history fallback algorithm, ensuring tabs are always grouped correctly — even in rare race conditions.
• Fixed issue with the 1-second delay mode sometimes failing to group.
• Updated the cancel shortcut to Ctrl+Shift+U (Windows/Linux) or Alt+Shift+U (macOS), to comply with Firefox shortcut rules.
• The cancel shortcut is now only active during the 1-second window and then automatically released — no interference with your system or other shortcuts.
