Hello There, In the history pane which could be opened by Ctrl + H shortcut, 'Forget About This Site' functionality creates impression to clear all history about that afformentioned site but it removes everything about the site including the passwords. I understand the perspective about 'forgetting' is different that i mention above but when you are in action like removing the passwords from the password manager you should clearly ask the user about this action. This functionality really bothered me and i try to disable it and i came accross with 'DisableForgetButton' policy which i thought that i would disable this feature and keep me safe from unintenional 'Forget About This Site' click in history pane but it wont. As a conculision; 1- I think Firefox should ask about the action with this critical level which is deleting the saved passwords in password manger 2- If you are not able to ask about this action you should allow users or system managers to control this ability.
