Hello, the default file manager for TDE is Konqueror, also Dolphin is available in the repos, is either of them capable of communicating with modern versions of Firefox to do things such as opening folders and selecting (highlight) the downloaded files?

Also, as I remember when I used TDE about a year ago, once a foreign file manager is installed (say Caja or pcmanfm) Firefox automatically starts using them to show downloaded files and forgets completely about Konqueror and Dolphin, I know that it's known bug in Firefox, but is there a tested work-around to fix that? Can a TDE user force Firefox to use Konqueror or Dolphin to open files?

So my msg contains two questions:

1) Can Firefox communicate with Konqueror or Dolphin to show/highlight my downloaded files and to access my folders?

2) Can I force Firefox to use Konqueror (or Dolphin) as my prefered file manager?
