• moderation + profiles — hover mod toolbar (ban/timeout/unban/delete), client-side automod, mute or block that carries a user across twitch and kick, profile cards with a searchable chat-log archive, one-click twitch clips.

• light + private — vanilla js, zero runtime deps, capped buffers hold memory steady over 8-hour sessions. no trackers, no analytics, no third-party telemetry; emotes + settings sync through heatsync's own servers only.

Is heatsync 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.

heatsync 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.

heatsync is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
