Features & Capabilities

Uses the https://Xposer.io API to show the product, the exact version and a full product vulnerability report for a given website. Have you ever wondered what version of Wordpress a site is running? Now there is an easy way to find out. The Xposer extension makes it convenient to call out to the https://xposer.io API from the website you are currently viewing. Just click the extension icon and click 'Expose'. The product and exact version of the website you are viewing will be revealed to you.

As a developer you can use this information to offer the owner of the site an upgrade of the detected product.

As a site owner you can check if you are running the most recent version of the product.

The version is not gleaned from the meta tags of the website, but by checking of key characteristics of each known product.

Wordpress
Drupal
Joomla
TYPO3
Concrete 5

More products and capabilities will be added in the near future.

Is Xposer Safe?

Risk impact

Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Xposer requires very minimum permissions.

Risk impact analysis details

Low Request access to the following domains: xposer.io

Risk likelihood

Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Xposer is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
