Link Highlighter — Deane

Highlights all links opened on any tab while the extension was toggled on. Geared towards recruiters, researchers, or anyone wanting to keep track of which links they've opened.

Use cases:
- A recruiter browsing candidate profiles on LinkedIn can instantly see which profiles they’ve already reviewed.
- A researcher can stay oriented in long-form content, seeing at a glance which pages, or even which sections, they’ve already explored.
- Or any situation where someone might want to keep track of which links they've visited (e.g. movies on Letterboxd, links on Google Search, etc.)

By default, this extension normalizes URLs by removing all query parameters and hash fragments. This is customizable under "Advanced Options".
