Sorry, quick tree list (by ID) was suppoused to be: addonsTree bookmarks bookmarks-view ca-tree configTree cookiesList crltree device_tree directoryTree editBMPanel_folderTree email-tree engineList folderTree folderTree foldersTree historyTree imagetree info_tree metatree orphan-tree permissionsTree placeContent placesList prettyDumpTree rejectsTree server-tree signonsTree treesetDump user-tree

I update, now with trees that don't have hidecolumnpicker="true": ca-tree configTree crltree directoryTree email-tree folderTree imagetree orphan-tree server-tree user-tree

The column picker makes a lot of sense: it notifies the user that the columns can be modified, and it's nice for people without right mouse buttons (Macs). So in the absence of a view menu or toolbar item (and who'd want to implement that for a certificate dialog?), the column pickers make sense... which basically narrows the field of makes-sense-to-remove pickers down to just the places library... ...and if you account for the fact that most of the things listed are very obscure and are not things that ordinary people will ever see (about:config? certificate manager?), then that too narrows it down to just the places library... which I thought had recently been fixed?

Right now, users might try to use one of the two approaches in the other scenario, which will fail. You have to decide which approach to use, and follow it consistently.

From bug 94407 comment 31, which in turn quotes my Ubuntu bug #306438: > Right-clicking on the column names in the address book > includes a "Delete" option in the menu.

There's no View menu to show/hide columns anywhere, like the certificate manager, about:config, or Page Info, except the Places Library. Right-clicking on the column headers doesn't work anywhere except the Library either, so we need to fix that (in a general way) before removing column pickers. Of course we could just backout the removal of the column picker (bug 429668) for consistency... The column picker is useful for indicating that there may be hidden columns, like the Library, or Page Info - Media. It's much less useful if all columns are visible already like in about:config.
