556254 - Change default option "Apply default to all message to all messages in the folder..." to NO

Status: RESOLVED INVALID

(Thunderbird :: Preferences, defect)

Description

[[:Aureliano Buendía]]

In bugzilla we have a lots of "bugs" that point to "the original characters were incorrect..." etc.
Often this "issue" type is related only to option  "Apply default to all message in the folder..." where messages are stored.

I don't remember the default value because I'm TB fan from 0.7.x release, but if today the default value is Yes, it's possible without no other regression to change by defaul to NO?

Pasquale, what is the pref ?

Comment 2

[[:Aureliano Buendía]]

Should be mailnews.force_charset_override

But I don't know how this global pref interact with property "Apply default to all
message in the folder..." that is defined at folder level (maybe set the init value on all folders on first install?).

Aureliano Buendía(bug opener):
Do you use prefs.js which contains mailnews.force_charset_override=true? (probably it's set by you via UI while you were using Tb 2 or former)
Or you use user.js which contains mailnews.force_charset_override=true?

Brief history.
1. Global mailnews.force_charset_override=true was introduced
   for users who receive many mail of wrong charset in mail header.
   Default is false since initial.
2. Per folder setting for ignoring wrong charset was introduced.
   Upon folder creation, mailnews.force_charset_override is probably used
   because it's user's request by global mailnews.force_charset_override=true.
3. As Magnus says, UI to change mailnews.force_charset_override was removed
   by Tb 3.0. mailnews.force_charset_override itself is not removed yet.
   Default is still false. Implementation around the force_charset_override
   is not changed. Only "remove from UI" was done.

Thanks for complete explanation Wada: my issue is related to an very old prefs.js with mailnews.force_charset_override set to true.

I try with a new fresh profile without the old prefs.js and I veryfied that TB work as expected (and you explain in comment #3).

This bug is Invalid because is my mistake.
