I have a problem with roboform working with firfox 4. Did the recommented upgrade and lost my data file
Roboform toolbar would not open up after install of Firefox 4. Followed Roboform advice to download their compatible version and then needed to pay for upgrade. Roboform continued to deny access and with many emails of suggestions back and forth I finally lost my data file. I would prefer to use an open source Password protection extension if there is one.
