I just accidentally deleted a day of history, now it has to relearn a bunch of stuff.

Please add support for undo, so that if you do it by accident, you can reverse it.

There used to be a much more useful interface for clearing specific browsing data (the landscape-oriented one). The new interface is far less detailed to the point of strictly limiting its functionality. There used to be a config setting ("privacy.sanitize.useOldClearHistoryDialog") that could toggle which interface to use, but as of an update in the last week (I've been away without a computer for a while), that toggle does nothing. Is there any other setting that can make this feature actually useful again?
