Addon for Opera: https://addons.opera.com/addons/extensions/details/roboform-lite/

Roboform's native Google Chrome extension is the only Roboform browser addon that isn't a toolbar. I suppose that if you only used Chrome, Roboform isn't that obtrusive.

However, only being able to save 10 passwords on the free version seems... crippling. Once again, I recommend LastPass.

Though Roboform is good for filling reward surveys, I would not tolerate its user interface in everyday use. Roboform installs a toolbar on all of your browsers. I hate toolbars.

I recommend Lastpass over Roboform, mostly because Lastpass only adds a small, unobtrusive icon to your browser's interface, while Roboform just has to stick their service right in your face with their unnecessary toolbars.

I found Roboform's form filler pretty useful for filling in surveys from rewards sites (I inputted false information, of course).

Roboform is available for FREE as Online and as portable Roboform2Go:
