Like other users here this has stopped working for me today. My Roboform icon is greyed out, I can view an error
"Could not establish connection. Receiving end does not exist."
I have used this for years and I use it many times per day. No changes to Firefox or update to the plugin on my end.
(Also, Im using Waterfox which has worked fine with Roboform until today)
I hope there is a fix soon.
