Worldwide Chat (WWC) sɣur LastHopeLabs

Worldwide Chat (WWC) adds a live chat panel to every website you visit. Everyone with the extension on the same site sees the same room — talk with people who are reading the same page, right now.

How it works

Open the chat bubble in the corner of any page.
Send a message, or set a nickname with /nick Name.
One room per website: lasthopelabs.com has its own room, reddit.com has its own — no mixing.
Features

Instant live chat with everyone on the same site.
Reviews tab: rate the site you are on (1-5 stars) and read what others think.
Light and dark themes.
Your identity is a random identifier (SID) stored in your browser: no account, no email, no password.
A possession key keeps your identity safe: nobody can reuse your SID from another computer.
Built-in anti-spam (rate limit per connection).
Privacy

Only the hostname of the page you are viewing is sent, to pick the right room.
Messages you send are delivered to people on the same site and stored temporarily (last 1,000 messages per room).
No ads, no trackers, no browsing history collection. Full policy: chat.lasthopelabs.com/privacy.html
Works on desktop and Android (Firefox 142+).
