Tab Timeline with Temporal Tracking and Quick Navigation Controls

[manojkumarlinux]

Summary:
Introduce tab-level temporal metadata and navigation controls to improve tab management and productivity for users who work with many open tabs.

Description:
When multiple tabs are open, it becomes difficult to track which tabs are recent, frequently used, or inactive. All tabs currently appear visually identical aside from title and favicon, which limits situational awareness and slows down workflows.

This proposal introduces a lightweight “Tab Timeline” feature that surfaces useful tab activity information via a hover tooltip.

Proposed Behavior:
When the user hovers over a tab, a small tooltip or overlay appears, showing:

• Opened: Timestamp when the tab was created

• Last Active: Most recent interaction or update time

• Time Spent: Total active time spent on the tab

• Access Count: Number of times the tab was focused

• Navigation Controls:

  • ← Previous tab

  • Next → tab

Example Tooltip:

Tab Info
Opened: 10:42 AM
Last Active: 11:05 AM
Time Spent: 23 min
Accessed: 18 times
[ ← Previous ]   [ Next → ]

Use Cases:

• Managing 20–50+ tabs efficiently

• Research or study sessions

• Development/debugging workflows

• Identifying stale or unused tabs

• Quickly switching between recently used tabs

Benefits:

• Better tab awareness

• Faster navigation

• Reduced cognitive load

• Cleaner session management

• Improved productivity for power users

Privacy Considerations:
       All tracking can remain local to the browser with no telemetry or external data collection.

Optional Enhancements (future ideas):

• Sort tabs by last active or time spent

• Highlight inactive tabs

• Auto-close stale tabs

• Tab statistics panel in Tab Manager

Thank you for considering this enhancement to Firefox.
