About this extension
FastWeb shows official alternate domains, your bookmarks, and accelerates link loading — right on Google, Bing, DuckDuckGo, and Yandex search pages.

Why FastWeb?

Some websites change domains, get blocked, or move to new addresses. FastWeb keeps a map of domain-to-alternate relationships so you never hit a dead end in search results. One click takes you to the working version.

What it does
  • Alternate domains — when a search result matches a domain in your list, FastWeb shows its official mirrors and alternates in a compact panel
  • Smart bookmarks — scans your bookmarks and shows relevant ones alongside search results
  • Link acceleration — warms up DNS/TCP/TLS for top results on hover. Pages load noticeably faster when you click
  • Domain bundles — curated bundle of popular alternates for your locale, auto-updates daily. Add your own or import JSON
  • Flexible display — full panel or compact icon-only badge

Privacy-first
  • All data stays in your browser — nothing is sent to any server except the optional daily bundle sync
  • No analytics, no tracking, no telemetry
  • Prefetch only warms up connections (DNS/TCP/TLS), never fetches page content
  • Bookmark data is read locally, never transmitted
