Just a heads up before you update to FF4!
When I updated to FF4 RoboForm 6 stopped working.
No problem, when I bought Roboform they promised updates are free for life. Went to update and Siber Systems want some money!
A quick search shows there's a lot of unhappy people at the moment, even talk of a class action.
Anyway life's too short, bye-bye Roboform hello LastPass which is free (for now!)
