## Who

I still hit LinkedIn people-search pages where the work is repetitive Connect clicks, and I still want the delay, the stop button, and the weekly ceiling visible before the loop runs away.

For operators who load-unpacked a tiny MV3 tool on their own account, not a SaaS growth bot.

## What

I shipped **ConnectedIn**, public https://github.com/michaelmonetized/ConnectedIn. HEAD `a6236fa`. **2** commits. Version **1.0.0**. Manifest V3 popup + `content.js` clicker.

![Content loop](/blog/connectedin-mv3-linkedin-auto-connect-chrome-extension/screenshots/content-loop.png)

Popup: delay input (100–5000ms, default 500), Start/Stop, clicked/remaining stats, yellow ~1,100 connects/week warning. `chrome.storage.sync` keeps delay + stats. Content script filters `button[type="button"]` whose trimmed text is exactly `connect`, clicks with `setTimeout` spacing, posts `updateStats` / `finished` messages.

![Manifest gaps](/blog/connectedin-mv3-linkedin-auto-connect-chrome-extension/screenshots/manifest-gaps.png)

Honest gaps on day one: manifest declares icons under `images/` but **no images directory**; **no `content_scripts` entry** so `content.js` is not auto-injected; popup `sendMessage` has nothing to talk to unless something else injects the file. `scripting` permission is unused.

![Rate limit](/blog/connectedin-mv3-linkedin-auto-connect-chrome-extension/screenshots/rate-limit.png)

README + INSTALL.md document LinkedIn’s weekly ceiling, delay bands, and that automation sits awkwardly against LinkedIn ToS (personal-use framing only).

## Where

Code: [github.com/michaelmonetized/ConnectedIn](https://github.com/michaelmonetized/ConnectedIn), public MIT.

```bash
git clone https://github.com/michaelmonetized/ConnectedIn.git
# chrome://extensions: Developer mode, Load unpacked, select folder
# open linkedin.com people search, click extension, Start Clicking
```

## When

**2026-03-21 15:30 ET.** init (+548, 7 files).

**15:31 ET.** INSTALL.md (+147). HEAD `a6236fa`.

Queue `pushed_at` **2026-03-21T19:31:06Z**.

## Why

A Connect clicker is only useful if the delay and the weekly ceiling are first-class, and if the manifest actually wires the content script.

**Engagement Q:** Fix `content_scripts` + icons first, or rewrite the selector against today’s LinkedIn DOM?
