Just Black is safe to use. It does not request any sensitive permissions.
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, bypass your security settings, and access your personal data. High risk
impact extensions are not necessarily malicious. However, if they do turn
malicious, they can be very harmful.
Just Black has earned a good reputation and can be trusted.
Risk likelihood measures the probability that a Chrome extension may turn malicious.
This is determined by the publisher and the Chrome extension reputation on Chrome Web Store,
the amount of time the Chrome extension has been around, and other signals about the
Chrome extension. 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, especially ones with higher risk impact and/or
higher risk likelihood.
I love it but theres some things that may be a little unhelpful, it seems to me that you cannot install these themes and extensions on school managed accounts, and its becoming very annoying. if there was a way to make those themes unblockable then that would be great. overall i love the themes :)
The manifest file declares the requirements and permissions that
a Chrome extension will have access to. By reviewing the manifest, you may be able
to determine if a Chrome extension is over-reaching (for example, if an extension
is overriding your new tab page, or search provider, or requesting access to your web activities
without any good reason).
