Tempx — Temporary Email — tempx

Tempx is a free temporary email service (tempx.uk). This official companion puts a disposable address in your Firefox toolbar — so when a sign-up form asks for an email, the answer is one click away.

• Instant address — one click generates a random temporary email like swift-otter-42@tempx.uk. No sign-up, nothing to configure.
• One-click copy — the address is always in the popup, ready to paste
• New-mail badge — the toolbar icon counts unread messages, checked about once a minute while Firefox runs (you can pause it)
• Fresh start anytime — "Get a new address" swaps in a new random name
• Same inbox everywhere — "Open inbox on Tempx" opens the exact inbox you generated or connected
• Private option — token-protected inboxes can be connected from tempx.uk in one step
• Light & dark — follows your system theme, switchable by hand
• Reading stays on the site — message contents are never shown inside the extension

Privacy, plainly: only storage, alarms, and tempx.uk permissions — no analytics, no trackers, no ad SDKs. The extension stores your address and message counts, not message contents; mail is read on tempx.uk. Free, no account needed.
