thank you for your response. It appears that this action is designed into RoboForm as noted in this response from RoboForm support

"Natalia replied (2017/12/28 10:09 am EST) Hello Philip,

The behavior described by you is by design in Chrome and Firefox. A user can disable RoboForm extension to enable the built-in password manager in the browser. The user is intended to use either at a time, not both.

I am glad to hear that your problem has been resolved. If you haven't already, *Please select the answer that solves the problem* YOURS. This will help other users with similar problems find the solution more easily. Thank you for contacting Mozilla Support.

That's really stupid! There is no conflict between the two. For years, I have used Firefox as my primary 'form filler' while using Roboform for higher security passwords. As the USER I should be able to choose between the legacy behavior and this new "I know what's best for you" behavior.

Thanks for the answer. They both work fine in Firefox 53, so Ill just go back to it and the hell with security.

At least consider using Firefox 52 ESR so you will get security updates for a while still and not be so vulnerable with the old Firefox 53.0.3. The 52.9.0esr out on July 3rd is likely to be the last update.

It seems that freedml and rckmns have pointed to the answer. What did FF change between 53.0.3 and the latest versions. Like freedml, I too have always used both Firefox as my primary 'form filler' while using Roboform for higher security passwords and the problem still exists even without Roboform as an extension. Thus it is an issue in FF. Mozilla needs to look at what controls the memory of that option and find out what has changed between 53 & 59
