1) RoboForm works in Maxthon 3 in Trident mode. While the default engine the browser uses, WebKit, no longer works with RoboForm, if you click the "Lightning bolt" near the address bar, this will change it to the Trident engine. RoboForm will then automatically attach as normal. Click the RoboForm Taskbar Icon in your system tray >> Show Toolbar.
2) RoboForm also works in these Browsers based on Internet Explorer (MSHTML):
a) MSN browser: only the Lower RoboForm Toolbar is available
b) Avant Browser
c) NetCaptor: upper toolbar works
d) SlimBrowser: upper toolbar works
