57 Now that you have Firefox running with logging enabled, please try to
58 replicate the bug using the steps to reproduce from the bug report. Once
59 you have reproduced the bug, shut down Firefox. Close out of the command
60 prompt/shell/Terminal, and then launch Firefox normally. Finally, attach
61 the cookie-log.txt file to the bug where it was requested (by clicking
62 on Create New Attachment). It should be in C:\temp on Windows, your home
63 directory on Linux, or the Desktop on Mac OS X.
65 Thanks for helping us make Firefox better!
