hello, please install the latest available (&compatible) version of roboform: http://www.roboform.com/download

Thanks Phillip, I keep Roboform constantly up to date. I went into Extensions instead of Addons in Firefox (where Robform didn't appear) and lo & behold there was my Roboform toolbar with Firefox telling me it's not to be trusted and had disabled it. Well, that's my decision to make, so I enabled it again and it works fine. Thanks for your quick respons, though. Roboform users, don't be tricked into thinking Roboform toolbar is an addon or believing the Firefox message about diabling your add-on. It's an Extension. Pedantic semantics but it might stop someone else panicking as I did!

Extensions, Plugins and Themes are all Add-ons!
