1434577 - Tabbing from address entry field is lower-casing the user name

Status: UNCONFIRMED

(Thunderbird :: Message Compose Window, defect)

Description

[finnian]

User Agent: Mozilla/5.0 (X11; Ubuntu; Linux x86_64; rv:58.0) Gecko/20100101 Firefox/58.0
Build ID: 20180123173120

Steps to reproduce:

I entered the email address

[e-mail]

and then pressed TAB to go the to the subject line.


Actual results:

The user name in the address field is lower-cased

[e-mail]




Expected results:

The case of the user name should be preserved because email user names are case-sensitive, and it will affect the deliver-ability.

Pressing TAB will certainly NOT make what you entered lower-case. What is likely happening is that you have Karen already somewhere in lowercase in the address book and when you press TAB, that version is accepted via autocomplete.

BTW, e-mail addresses are practically NOT case-sensitive. Please read the article you quotes under the heading "Case Typically Does Not Matter".
