This is a bug report.
The 4.0 version of Konqueror does not support plug-ins. It does not support Adobe flash player, and it does not support Java enabled web sites. I am assuming that is does not support any plug-ins, but I’ve not performed exhaustive testing. I am able to get both plug-ins to work with Firefox in SuSE 11.0. I was able to get both plug-ins to work with Konqueror in SuSE 10.3.
Then please go to bugs.kde.org, check whether anyone else has reported it and, if not, report it.
That will help us all. Thanks.
