Unsigned

A Chrome / Brave / Edge extension that strips the sharer-tracking tags X adds to copied tweet links, and can optionally hand you a vxtwitter (or fixvx / fxtwitter / fixupx) link instead.

X gives:  https://x.com/CapStasher/status/1984351689248502248?s=12&t=dHJhY2tlZC10b2tlbg
Clean:    https://x.com/CapStasher/status/1984351689248502248
Embed:    https://vxtwitter.com/CapStasher/status/1984351689248502248

The t= value is a session-bound token that identifies whoever copied the link; s= marks the client it came from.

Install

1. Download unsigned-<version>.zip from Releases and unzip it into its own folder somewhere permanent.
2. Go to chrome://extensions (or brave://extensions, edge://extensions) and turn on Developer mode.
3. Load unpacked → pick that folder.
4. Reload any open x.com tabs.

Needs version 111 or later.

Use

Click ⋯ / Share → Copy link on a tweet as normal. The toolbar seal flashes ✓ (clean) or vx (embed) when a link was rewritten.

• Mode — Clean or Embed, from the toolbar popup. Embed service is selectable.
• Shift-click "Copy link" to use the other mode for that one copy.
• Scrub rich copies — also removes the hidden tracking spans X slips into the HTML side of ordinary text copies.

Embed conversion only happens when the copied thing is a single tweet link. Links inside copied prose are cleaned but stay on x.com.

How it works

src/hook.js runs in the page at document_start and wraps every route X can use to write the clipboard: navigator.clipboard.writeText / write, clipboardData.setData inside copy/cut handlers, and plain execCommand('copy') of a selected link. The rewrite rules live in src/rewrite.js. src/bridge.js relays settings in from extension storage (the page context can't read it).

No network requests, no analytics, nothing stored but your settings. Permissions: storage, plus access to x.com / twitter.com.

Building

The repo root loads as-is via Load unpacked. To produce the release zip:

node build.mjs

This writes dist/unsigned-<version>.zip. No dependencies.
