We have a financial solution written in Java, which contains various functions and fields which the users have to complete. Version 67.0 has resulted in the fields not being cleared as one navigates between the functions and fields... and precompleted data populating fields can result in a huge financial impact for our clients.

Version 66.0.5 worked fine and none of these problems were encountered. 

I have tried under "privacy settings" and unticked the filed for the Pre-completion of forms, but that doesn't have any effect. does someone have other alternatives or suggestions what else we can check or might this be solved with a future Firefox Upgrade
