That call originated in bug 1270018, if I'm reading the history correctly. (There's been some noise since then with changes to configure flags, NPAPI removal, etc.)

That call originated in bug 1270018, if I'm reading the history correctly. (There's been some noise since then with changes to configure flags, NPAPI removal, etc.) Edited to add: “that” call to `DeleteDirIfExists`; there was earlier code to do something similar, so maybe bug 1270018 is also too recent.
