Profile

BrowserTotal provides a secure extension marketplace that looks and feels just like the official vendor stores (e.g. Chrome Web Store or Firefox Add-ons). Users can browse extensions through BrowserTotal’s interface, which acts as a live mirror to the vendor’s marketplace. This means the extension listings, descriptions, and visuals are identical to the original store from the user’s perspective. The key difference is that BrowserTotal’s security analysis engine is transparently injected into the session, enabling real-time scanning of the extension before you install it. In other words, you get the same marketplace experience, but with an extra safety layer added behind the scenes.
