Job Ad Marker by Ivo Stoykov

Job Ad Marker is an extension for Chrome and Firefox that marks LinkedIn job cards and blacklisted company profiles. It helps you work through large job lists faster by marking adverts you have already seen, jobs you have applied for, companies you do not want to deal with, and older listings you may want to skip.

The aim is simple: reduce repeat scanning. Instead of re-reading the same cards every time LinkedIn reshuffles, reloads, or promotes old listings again, the extension adds lightweight visual cues directly to the job list.

Works with content already loaded on the LinkedIn pages you open. No automated browsing or data sent to developer servers. Settings and company blacklists may sync through your browser account.

Marks and notes are for your own reference. The extension does not submit applications, send messages, save or unsave jobs on LinkedIn, or change your LinkedIn account's application status. Mark as applied only updates the extension's saved marker. Company blacklisting is a personal preference, not a report to LinkedIn or a shared rating of an employer.

On supported LinkedIn job pages, the extension scans job cards, extracts job identity where available, and compares that against locally stored data.
