Doesn't even work! It's so frustrating that I can't pass by environment check as it keeps logging me out. I'm not trying to fail my class but this stupid lockdown browser doesn't even work.

One star is generous. It either lags or freezes whenever I use it and I have also had one instance of being unable to type in the text boxes. Thankfully my professor allowed me to submit my responses through email or I would have bombed my exam. I hate this browser so much!

Extension safety

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.

LockDown Browser requires a lot of sensitive permissions. Exercise caution before installing.

Risk likelihood

Risk likelihood measures the probability that a Chrome extension may turn malicious.

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 Chrome extension.
