Is it possible to embed firefox into konqueror.

I wonder to preview web pages in konqueror with firefox as i'm currently
previewing text files with kate and videos with dragon ?

Yes, this definitely can be done. Right click on an HTML file, click "Properties" and click the button with the icon of a wrench for "Type". In the list, select firefox and click "Move up" and send it to top. This should make your html files open in Firefox.

Kate etc. are using KParts. The classes for the Application-Windows inherit KXmlWindow, with a few XML-Information they can be embedded into another KDE-Application. Also shortcuts, menus etc. are available inside of Konqueror.
But Firefox:
-does not use KParts
-does not use KDE
-does not use Qt
-does not provide Qt-compatible Signals and Slots
-does not provide a DBus-interface
Firefox still uses the X-Server, but it would be really a hack. It is possible to render X-Windows inside of Qt-Widgets, but that would not be a real integration. Maybe it would be hard to provide the same Addon-API like Firefox, but a comfortable integration would be nearlly impossible. (integrating Gecko maybe would be easier)

I don't mean "my html files open in Firefox", I mean "preview" with firefox in konqueror.

You cannot do that, currently.

"Preview" in Konqueror means there is a KDE component (a KPart) able to display a type of file(s). In this case, it should be a KPart for rendering HTML pages using the Firefox' engine (Gecko).
There was an attempt to create one years ago, but due to lack of support from Mozilla community and complexity of the project it was not developed further.
