User Reviews

Reviews are mixed but lean negative: many users report frequent connectivity failures and very slow, often unusable speeds. A few users say it sometimes works and are satisfied, but others report failures on portable and mobile Firefox builds and raise privacy/security worries (WebRTC leaks and broken URL encryption). Overall reliability and performance are the main complaints.

Pros

Some users report the extension works and are satisfied (several short positive reviews).
The add-on can function intermittently — reviewers note it does connect and allow access at times.
When it works for a user, it can provide proxy access to reach blocked sites (reported by multiple users).

Cons

Frequent connection failures and general unreliability (many reviewers say it often does not connect).
Very slow speeds or unusable data streams when a connection is established (several reviews).
Problems on non-standard installs and mobile: portable Firefox and Android Firefox reported not to work.
Privacy/security concerns: reports of WebRTC IP leaks and URL-encryption breaking (multiple reviewers raised leak/encryption issues).

Is KProxy Extension for Firefox 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.

KProxy Extension for Firefox requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.
