Recent reviews
This extension is only semi-useful... It only sporadically works when at team page at sleeper, and it doesn't update advice when I already have changed lineup in another tab (YES, I clicked on "update advice" when an error popped up after trying to submit lineup on sleeper through this addon):

Is FantasyPros: Win your Fantasy League 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.
FantasyPros: Win your Fantasy League requires a lot of sensitive permissions. Exercise caution before installing.
