Survol is a free, open-source browser extension designed to save you tabs and time by generating instant previews of hyperlinks when you hover your cursor over them. Created by developer mdolr, it provides quick snapshots of external content so you do not have to open countless background tabs just to see if a link is worth visiting. How Survol Works
Metadata & API Extraction: The extension gathers data dynamically. For websites with dedicated APIs, it pulls rich, interactive data. For basic web links without tailored APIs, it extracts standard metadata (like page titles and descriptions) to create the preview.
Hover-Activated Modals: Hovering your mouse over any URL surfaces a floating preview card.
Open Source: The full code is auditable and available on the Survol GitHub Repository. Where to Find It
You can download the extension directly from the Official Survol Website or install it through the Firefox Add-ons Marketplace. Important Context: Built-In Firefox Alternatives
If you are looking for “ultimate web link previews” specifically on Firefox, you should note that Mozilla has officially integrated native, on-device AI link previews directly into the browser, meaning you may no longer need a third-party extension like Survol. The built-in Firefox tool offers advanced capabilities:
On-Device AI Summaries: The browser uses a local, privacy-focused WebAssembly LLM (wllama) to pull text and instantly generate 3 key bullet points from a webpage without compromising your data.
Rich Preview Cards: Displays a snapshot containing the page title, description, an image, and an estimated reading time.
Native Hotkeys: Instead of triggering on every single hover (which can get annoying), you can easily summon the native preview by hovering and pressing Alt + Shift (Option + Shift on macOS).
How to turn on Firefox’s native tool: Navigate to your Firefox settings, select the Firefox Labs section, and check the box for Link previews.
Are you hoping to preview a specific type of link (like social media profiles, YouTube videos, or code repositories), or are you trying to resolve an issue with standard link hover spam?
