RandomUA Firefox

RandomUA

Changes your User-Agent string to a sensible-looking string which is different for every request. Having a different UA on each request make it a lot easier to evade some tracking schemes. Supports excluding certain domains, and mobile-like UAs.

Features & Capabilities

RandomUA changes your User-Agent string to a sensible-looking, desktop-browser-like UA string which is different for every request.

Many browser fingerprinting solutions use the User-Agent as a relatively constant string, because most users UAs only change when their browser updates. Therefore, having a different UA on each request make it a lot easier to evade these tracking schemes.

RandomUA requires access to all URLs and web request data for its core function: it has to be able to change your user agent string!

Is RandomUA 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.

RandomUA requires a few sensitive permissions. Exercise caution before installing.

Risk impact analysis details
  • Critical Allows access to all websites, posing a significant security risk as it can monitor and modify data from any visited site.
  • High ****** *** ********* ** ******* *** ******* ******* ** ****** *** *** ******** ******
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.

RandomUA has earned a fairly good reputation and likely can be trusted.
