If, like me, you have trouble remembering your user and account names and passwords for all the different sites, accounts and logins that you frequent,
Roboform is a great aid.
You never need to remember anything again - it automatically senses when logon details (and other details in other forms, if you wish) are required and fills them in for you at the click of a button.
There are security issues with this, of course. Eg if your lappy gets knocked off the thief would have ready access to whatever you had set up in Roboform. But they've thought of that; you can password-protect Roboform itself - yes, you will have to remember a password, but
only one!
It also comes free with
Slimbrowser, my choice of tabbed browser.
