h3>What it does <p>Fresh Eyes remembers the pages you visit. When you come back to a page, it highlights exactly what changed since your last visit — new sections in green, edited sections in amber — and tells you the difference at a glance.</p><h3>Why you'll like it</h3> <ul> <li><strong>Stop re-reading.</strong> Docs, wikis, changelogs, news articles, product pages: you see the delta, not the whole page.</li> <li><strong>Guided walkthrough.</strong> A small toast shows "5 changes since 2 days ago" with a "Next change" button that scrolls you through every highlighted section.</li> <li><strong>100% private.</strong> Page snapshots live in your browser's local storage. Nothing is uploaded anywhere — the add-on has no network permission at all.</li> <li><strong>Zero setup.</strong> No accounts, no configuration. Visit a page once to set the baseline; the second visit shows the changes.</li> <li><strong>Smart and quiet.</strong> A noise filter ignores ads, navigation, footers, cookie banners and comment sections, and always-changing sites (social feeds) can be ignored entirely.</li> </ul><h3>Features</h3> <ul> <li>Automatic highlight of added and modified sections on revisit</li> <li>Toolbar badge with the number of changes on the current tab</li> <li>Popup with per-change previews, "Re-highlight" and "Mark as read"</li> <li>"Next change" walkthrough from the in-page toast</li> <li>Noise filter + configurable ignored-sites list</li> <li>Mark as read resets the baseline instantly</li> <li>Automatic pruning of old snapshots (60 days / 2000 pages, configurable)</li> </ul><h3>Privacy & permissions</h3> <p>Fresh Eyes stores only text hashes and short text fragments of the pages you visit, in your browser's local storage. It never sends data anywhere, never tracks you across sites, and deletes everything when uninstalled.</p> <ul> <li><strong>storage</strong> — saves page snapshots and settings locally</li> <li><strong>tabs</strong> — shows per-tab change counts in the toolbar</li> <li><strong>Content scripts on all sites</strong> — needed to snapshot page text so changes can be detected; the add-on only reads text and never transmits it</li> </ul><h3>FAQ</h3> <p><strong>What counts as a change?</strong> Text blocks (paragraphs, list items, headings) that are new, deleted, or edited since your last visit.</p> <p><strong>Does it work on YouTube or Twitter?</strong> By default those are ignored — they change constantly. You can edit the ignored-sites list in Options.</p> <p><strong>Does it upload my pages anywhere?</strong> No. There is no network permission in the manifest.</p> <p><strong>How much storage does it use?</strong> Snapshots store hashes and short text fragments, pruned automatically (default 60 days / 2000 pages).</p>
