Following an upgrade from Firefox 6.0.2 to Firefox 7.0, this error appeared in response to accessing Firefox! Executing an auto log-on produces the following error message: XULRunner-Couldn't load XRE functions. Also, following an upgrade from V7.0 to V7.0.1, the same error occurs. Following the In-place Upgrade from Vista Home Premium x64 to Win 7 HP x64, the RoboForm2Go taskbar is no longer on the program display page, rather it is confined to the bottom taskbar. This is likely due to a reported incompatibility between Roboform2Go and Firefox v7.0 (and 7.0.1). Further, there was a failure of RoboForm2Go Log-ins from the bottom quick-start taskbar.
