(but I only use IE for an internal work-site that uses ActiveX stuff, phew)
Just out of curiosity I notice MS has decided not to support ActiveX in Edge. I wonder if MaxThon does or will continue to support ActiveX? I used it back in v 2.0 when unsigned AddOns were still allowed. So I am not aware of the current state of MaxThon browser vis a vis ActiveX Controls, BHOs etc..
Edit: A quick search found a fix in the MaxThon 4.x changelog for "automatically switching to Retro Mode" when encountering ActiveX. So evidently it is grandfathered in.
