Review summary

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).

2023-11-01	Ke*****	Рекомендую! Работает всё очень хорошо, даже в режиме санкции. Да, не очень быстрое соединение. Но работает и на канадском сервере и на французском хорошо. Пришлось уйти от расширения BROWSEC, потому что она не стала работать в режиме санкций. Ну нет и не надо! ----------------------------------------- I recommend! Everything works very well, even in sanctions mode. Yes, not a very fast connection. But it works well on both the Canadian server and the French one. I had to abandon the browsec expansion because it did not work in the sanctions regime. Well, no and don’t!
