LinkedIn Post Scraper Chrome Extension

A reliable Chrome extension for exporting recent LinkedIn profile posts and company page posts to CSV, with a persistent queue, configurable limits, pause/reset controls, and resilient feed scrolling.

Overview

LinkedIn Post Scraper Chrome Extension helps you collect public LinkedIn activity from:

• Personal LinkedIn profiles via /recent-activity/all/
• LinkedIn company, school, and showcase pages via /posts/?feedView=all

It is designed for researchers, sales teams, founders, recruiters, content analysts, and developers who need a practical way to export visible LinkedIn posts from a browser session they control.

The extension runs in your own Chrome profile, uses your active LinkedIn login session, and exports one CSV per queued profile or company page.

Reliability Design

LinkedIn feeds are dynamic and virtualized. This extension uses several strategies to make scraping more reliable:

• Collects posts incrementally while scrolling.
• Deduplicates posts using post URLs, activity URNs, and content fallback keys.
• Avoids clicking LinkedIn post/media links while expanding text.
• Stops when the selected post limit is reached.
• Stops when explicit no-post/no-activity text appears.
• Stops when the page bottom is stable and no loader is visible.
• Stops when scroll position, page height, and collected post count remain unchanged for about 10 seconds.
• Uses per-profile time budgets so the queue can continue if one page behaves badly.
• Uses run IDs and cancellation messages so pause, clear, and reset do not save stale scrape results.

Permissions

The extension uses these Chrome permissions:

• tabs: open and reuse a LinkedIn tab.
• activeTab: interact with the active browser tab.
• scripting: inject/retry the content script when needed.
• storage: persist queue, logs, settings, and status.
• downloads: export CSV files.
• alarms: resume queue processing after service worker suspension.
• declarativeNetRequest: enable optional performance mode by blocking heavy media/font requests during scraping.

Host permissions are limited to:

["*://www.linkedin.com/*"]

Responsible Use

This project is intended for lawful, ethical research of data you are allowed to access. LinkedIn may restrict automated collection under its terms or rate-limit suspicious activity.

Do not use this extension to collect private data, bypass authentication, evade access controls, spam users, or infer sensitive personal traits. You are responsible for complying with LinkedIn's terms, privacy laws, and all applicable regulations.

Troubleshooting

• Nothing scrapes: Confirm you are logged in to LinkedIn.
• Company pages return too few posts: Use /posts/?feedView=all, turn Performance mode off, and retry.
• Profile has fewer posts than your limit: The scraper saves what it finds and moves on.
• Popup looks stale after an update: Reload the unpacked extension in chrome://extensions.
• State gets messy: Use Reset Extension in the popup.
• LinkedIn layout changes: Selectors may need updates in contentScript.js.
