Version: (using KDE 4.3.1) Installed from: Debian testing/unstable Packages Konqueror loads up the last webpage after it was forcefully killed (e.g. for Bug 207379), which will freeze again, going into a loop. Firefox asks the user if the last website should be opened, something Konqueror did before, too, if I remember correctly.
This is a partial case of the following request: bug#51505
Hmm... Konqueror already prompts you to restore a previous session if it was not shutdown properly ; so I fail to see what you are asking for here. The ability to select which one of the previous tabs should be restored ?
Starting with KDE 4.10, you will be able to choose which session to restore and which ones to discard. See http://git.reviewboard.kde.org/r/106503/. *** This bug has been marked as a duplicate of bug 260282 ***
