User Reviews

This extension is extremely useful. However, since the latest update, I've encountered a bug where the input field fails to appear when launching Firefox, and the address bar enters an infinite refresh loop. Because of this, I've reverted to the previous version for now. Are you aware of this issue, or could it be something occurring only on my end?

Creepy! Try asking a powerful AI if this extension is safe? It has all the characteristics of a major danger for the exfiltration of your data! Access to browser's tabs Access to your data for api.ipify.org WHY? Access to your data for discord.com WHY?

Is Browser Lock 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.

Browser Lock requires a few sensitive permissions. Exercise caution before installing.
