Tab Cemetery Timer от Abhishek kumar

Tab Cemetery gives each Firefox tab a clear time limit without dashboards or complicated settings.

Features:

• Quick timers: 1 minute, 5 minutes, 15 minutes, 1 hour, and 1 day
• Custom durations from 1 minute to 30 days
• Pause, resume, reset, and clear timers
• See remaining time for every timed tab
• Recover the original tab after expiry
• Lightweight popup designed for older computers
• No accounts, analytics, ads, or external servers
• No audio or tone features

The extension stores timer information inside Firefox and does not transmit browsing data.
