Sounded good. But it clearly doesn't do what it's supposed to on some websites like Civitai, the nb1 website for all fine tuned generative AIs. If you have 2 gmails accounts for 2 Civitai accounts, Civitai will constantly connect to the same gmail. Even after "clearing" website data. Too bad :/

Is Clear Website Data 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.

Clear Website Data requires a few sensitive permissions. Exercise caution before installing.
