User Reviews

IndicateTLS is praised as a reliable and user-friendly Firefox add-on for quickly viewing TLS/SSL security information, replacing older tools effectively.

Serves as a good replacement for older TLS checking add-ons like SSLLeuth and Calomel SSL.
User-friendly layout that makes TLS configuration easy to understand.
Helpful for security-conscious users to check site security details.

Cons

Concerns about the extension's extensive permissions and access to browsing data and saved passwords.
Requests for additional features like support for eSNI/SNI indication.
Suggestions for UI improvements such as choosing icon colors or repositioning the indicator next to the address bar padlock.

Is IndicateTLS 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.

IndicateTLS requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

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.

IndicateTLS is probably trust-worthy. Prefer other publishers if available. Exercise caution when installing this add-on.
