I have no experience building IE Extensions. I've found some posts that talk about it (for example this one looks pretty detailed), and I see that I need to read much more about this topic... :-)

But my question is not about how to build one. What I would like to know is: If I finally deploy an IE Extension, built in .NET:

  • Would my IE Extension / Add-On run in the same process than Internet Explorer?

I don't know if it would run in some kind of sandbox...

Thanks!

If in older IE versions, the answer is yes. For IE 8 and above, the answer is usually no.

  • Thanks @Lex Li ! Anyway... I've read the article and still having some doubts. It seems to be clear that in IE8 and above, each IE Tab runs in a different process... But I'm not sure if the ActiveX, Add-Ons run in different processes, or if they run in the same process of the tab... – Javier Mar 09 '12 at 12:11
  • The best way is to write a simple one and load it in IE, and see where you can find it. No post can tell you all the details more than a debugger such as WinDbg. – Lex Li Mar 09 '12 at 12:25
  • Mmmm..., after reading the link again, I guess that all the Add-Ons run in each tab, separatily, but sharing the tab process. But you are right, the best way to be sure is by testing it with a little sample. Thanks! – Javier Mar 14 '12 at 09:53
