Bug 878805 made some l10n string uses obsolete. According to MXR, msgFolderPickerOverlay.dtd from /mail/ doesn't get used anymore: http://mxr.mozilla.org/comm-central/search?string=msgFolderPickerOverlay.dtd&find=&findi=&filter=^[^\0]*%24&hitlimit=&tree=comm-central /suite/ uses the one from /suite/locales/en-US/chrome/mailnews/ There are some add-ons using the removed file (ignoring incompatible add-ons): https://addons.mozilla.org/en-US/thunderbird/addon/auto-save-drafts-folders/ by dlech https://addons.mozilla.org/en-US/thunderbird/addon/exquilla-exchange-web-services/ by rkent https://addons.mozilla.org/en-US/thunderbird/addon/copy-sent-to-current/ and https://addons.mozilla.org/en-US/thunderbird/addon/addressbooks-synchronizer/ by Neandr https://addons.mozilla.org/en-US/thunderbird/addon/unified-search-187593/ by IagoSRL https://addons.mozilla.org/en-US/thunderbird/addon/archive-this/ by Adam Roach https://addons.mozilla.org/en-US/thunderbird/addon/manualjunkaction/ by Ryan Lee

Comment on attachment 8366164 [details] [diff] [review] patch, v1 rs=me, although we'll probably want to post about this on tb-planning and mdat before landing it.

The folder picker specific strings are now being collected to folderWidgets.properties .
