Steps: 1. Create a folder or a bookmark on the Bookmarks Toolbar 2. Start dragging this bookmark or folder 3. Drop it onto itself 4. Hover over the bookmark or folder With step 4 you will see that the bookmark/folder appears as sunken when you hover it. This behavior is resetted when you perform a click on it. Any further hovering shows the normal hover state (half sunken). It also happens with Firefox 3.0.x on OS X.

I see following exception: Error: uncaught exception: [Exception... "Component returned failure code: 0x80070057 (NS_ERROR_ILLEGAL_VALUE) [nsINavBookmarksService.moveItem]" nsresult: "0x80070057 (NS_ERROR_ILLEGAL_VALUE)" location: "JS frame :: file:///Volumes/Minefield/Minefield.app/Contents/MacOS/components/nsPlacesTransactionsService.js :: PMIT_doTransaction :: line 558" data: no]

Yes, should have been done a better search. Thanks Ria.

Bug 451915 - move Firefox/Places bugs to Firefox/Bookmarks and History. Remove all bugspam from this move by filtering for the string "places-to-b-and-h". In Thunderbird 3.0b, you do that as follows: Tools | Message Filters Make sure the correct account is selected. Click "New" Conditions: Body contains places-to-b-and-h Change the action to "Delete Message". Select "Manually Run" from the dropdown at the top. Click OK. Select the filter in the list, make sure "Inbox" is selected at the bottom, and click "Run Now". This should delete all the bugspam. You can then delete the filter. Gerv
