Open the Library 1. History - Show all History 2. In the right-pane - delete the 'today' folder 3. Note is disappears from the Left pane - Expected I would think 4. Now browse some and note that in the right pane the 'Today' folder is re-added showing your history, but the left pane does not have the 'Today' folder. 5. Close/reopen the History Library as in step 1, now you have the 'Today' folder.

The re-added 'Today' folder in the right pane can not expand by dblclick until reopen the the History Library.

we were updating grouped queries only when they were roots, but in the left pane of the library they are simple children of a folder.

Comment on attachment 371351 [details] [diff] [review] patch v1.0 r=me, thanks

i simply added a null check on the observer, to be consistent with other observers (And because gc can do nice things to our no more used results)

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
