Bug 415460 added a query mDBGetTags that gets the tags from the DB using GROUP_CONCAT. nsNavHistoryResultNode.tags can use that query.

fix. however, need to sort the tag list in the query, but the aggregate func doesn't wanna pull the contents of the subselect in a sorted manner. eg, the comma-separated tags in this example are not sorted properly: select group_concat(title) from (select title from moz_bookmarks order by title) if you execute only the subselect portion, the titles are sorted properly.

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
