BuildID: 20011221 An rfc2822-compliant address often contains a display-name token. The RFC specifies that this should be either a single word or a quoted-string, though most mailers (including Mozilla) also accept a multi-word string, provided there are no metacharacters. If display-name contains metacharacters (quote or backslash) than the whole thing must be a quoted-string, with the metacharacters each escaped with a backslash. Mozilla follows this last rule when it creates a FROM header. For example if your identity has the following fields: Mail address: bill@tombstone.com Your name: William "Wild Bill" Hickcock Then your messages go out with this header: From: "William \"Wild Bill\" Hickcock" <bill@tombstone.com> But if your recipient is also using Mozilla, address is displayed *exactly* as it appears in the header. This looks uncool, and is seriously non-compliant with the RFC, which states that the backslash is "semantically invisible". Just as Mozilla adds the backslashes when it creates the header, it should remove them when it interpretes it. D Reproducible: Always Steps to Reproduce: 1. Set your identity as described above. 2. Send yourself an email. 3. View the message and click on the return address. 4. Choose "add to address book" Actual Results: Sender display name is ugly. And backslashes get added to the address book name. Expected Results: Sender display and address book entry should both match the original Identity Your Name field.

I can confirm the behaviour here, and can't find a dupe. related: bug 134277 (FIXED)

Bug 134277 describes this same problem in a different context. If it's not a dup, it's close enough. In any case, the build I'm running (20020721) does not have the bug as I reported it. In short, it's now fixed -- thanks! *** This bug has been marked as a duplicate of 134277 ***
