When starting up a Places build for the first time Firefox should show a progress indicator that shows what it is doing and how much time it will take. People will appreciate that and not think that Firefox is crashing. Currently converting to the new format... Bookmarks..... done. History..... done.

I'm going to call this a duplicate of the slow startup time bug. It really needs to faster. If we can't make it almost instantaneous, there will have to be some kind of UI. *** This bug has been marked as a duplicate of 325171 ***

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
