Browser compatibility Issue 5: Plugins and ActiveX_ browsers

As: whzeng@126.com

As we all know, IE compatible with Third-party programs using ActiveX technology, and Firefox,safari,chrome,opera is the use of NPAPI plug-in technology.

Both at the interface level, the plug-in interface level is lower (all are C function pointers), abstract interfaces and data types encapsulate the interactive logic of browsers and Third-party programs, but browsers and plug-ins are tightly coupled, while ActiveX masks processes and threading models, and is a loosely coupled interactive approach. This is why legitimate ActiveX in IE does not cause IE to crash, but the same functional plug-ins may cause the browser to crash. The difference in this feature is also one of the big differences in browser compatibility.

A common plugin or ActiveX on a Web page. 1. Flash,adobe provides these two types of plug-ins. Some users will always mention why Flash is playing normally under IE, but not on Firefox, Safari, Chrome, opera and Maxthon3. It is likely that the Flash plugin without NPAPI is installed.

3. Internet Banking ActiveX
