Version: (using KDE KDE 3.5.1) Installed from: SuSE RPMs Favicons worked for me well, but once I started fiddling with show/hide on toolbar /with success I mean, because when show/hide doesn't work favicons work ok/ I lost three of favicons. No apparent reason -- they've just gone. This is what I did -- I checked option in Konqueror to show only marked bookmarks on toolbar. Then I chose to show several icons -- and just after selecting each icon the favicon disappeared.
KDE 3 is no longer maintained. If this problem is still present in KDE 4, feel free to reopen this ticket.
