Starting with version 138, released in April, Firefox introduced a new but currently disabled feature that leverages “artificial intelligence” to generate a small preview of a linked webpage.
This functionality analyzes the target page’s content and pops up a preview window, helping users steer clear of potential scams or malware from unsolicited links. The AI-driven preview runs locally on your device and does not rely on cloud services, as clarifies Mozilla.
To enable this feature, navigate to the URL about:config
, accept the security warning by clicking “Accept the Risk and Continue,” then search for the setting named browser.ml.linkPreview.enabled
. If it’s not already set to true, click the toggle button with the two arrows to activate it, then restart Firefox.
To view a link preview with AI assistance, either hold down the Shift key while hovering over a link or click and hold on the link. After a brief moment, Firefox will display a preview image along with an AI-generated summary of the linked page’s content, providing a safer browsing experience.
