What our analysis found
FasterWeb, used by 100,000 people, is rated caution by Extension Auditor. Our code review reported 2 findings (1 high, 1 medium), led by unauthorized data collection. Its permissions mean it can read and change data on all websites.
Key findings
- high· unauthorized data collection —The extension collects diagnostic and user data including browser information, system details, and if logged in, the user's email, and sends it to the publisher's server. The Chrome Web Store listing for this extension indicates no data collection, making this undisclosed data collection.
- medium· other —On extension update, a new tab automatically opens to a promotional website () without user consent. This behavior is unexpected and could be considered intrusive advertising.
The extension's core functionality (link prefetching) is benign and it communicates only with the publisher's own API (). However, it collects system information and, if authenticated, user email without declaring data collection in the Chrome Web Store listing. Additionally, it opens an unsolicited promotional tab on update. No evidence of third-party tracking or malicious code injection was found.

About this extension
Browse the web faster.
Read the publisher’s full description
FasterWeb uses just-in-time preloading, which preloads a page right before you click on it. In addition, FasterWeb enriches search results by adding the smart search widget beside the search results. The FasterWeb works best on pages on the same sites. Pages to external sites are still faster but more is needed to be noticeable. How it works: Before clicking a link, hover your mouse over it. When you have hovered for 65 milliseconds, there is one chance out of two that you will click, so Faster Web starts preloading at this moment, leaving on average over 300 ms for the page to preload. Pages that trigger an action (such as logging out or deleting something) are excluded. (FasterWeb won’t preload pages with a “?” in their URL.) FasterWeb — previously called FasterChrome — is based on instant.page, a library that you can add to your site in just one minute to give it the same speed boost. ADS When using FasteWeb, you may encounter ads for other extensions and affiliate links. These situational ads allow us to develop the product and make it free. Made with ❤️ by BrowseCraft gang.
