# Temporary Containers

15 Hacker News commenters recommended Temporary Containers and 1 criticized it, November 2025 to November 2026. It was recommended in 5 of 13 months. It meets the Hacker Approved badge rule.

**Verdict:** Firefox add-on that opens sites in disposable containers so each session starts clean and stays separated from others. Critics note it has been unmaintained and once corrupted a Firefox profile.
