覺得thunderbird做個note工具很不錯，但是每次新建一個mail，上面的from, to 都好大啊。。。
google了N次，想找個addon，但是沒找到，打算自己做一個
下載了tb8.2源碼，Highlighter 插件參考
Thunderbird's user interface is written in XUL and JavaScript
https://developer.mozilla.org/en/Extensions/Thunderbird
Tutorial: Building a Thunderbird extension , 就是讀的這個..贊，讀完就懂了

# Overlay and styles for the formatting toolbar
style chrome://messenger/content/messengercompose/messengercompose.xul chrome://highlighter/skin/format-tb.css
overlay chrome://messenger/content/messengercompose/messengercompose.xul chrome://highlighter/content/format-tb.xul
（表示把後面一個文件 merge到前面一個文件, 前面一個是tb標準的xml, 在tb源碼 /comm-beta/mail/components/compose/content/messengercompose.xul）
messengercompose.xul:
這個被merge進去.
安裝測試方法
直接放在：
.thunderbird/vmejnq0q.default/extensions/resizer-compose-header/
Using a text file to reference your extension files (recommended):
The file must contain a single line with the absolute path of the extension:
C:\Documents and Settings\\My Documents\Code\Thunderbird Extensions\[email protected]\
The text file's name must be exactly the same as the id of the field in the install.rdf file.
packaging 發佈：
Zip the contents of your extension's folder (not the extension folder itself), and rename the zip file to have a .xpi extension.
cd ~/extensions/my_extensions
zip -r ../sample.xpi *
工具：
To view this XUL file use theDOM Inspector extension or look inside the omni.jar archive
sdk：其實不用sdk了， 上面的步驟都不需要sdk https://addons.mozilla.org/en-US/developers/tools/builder
有online: offline
addon: developer assister
我需要的功能關鍵在於：
var headerToolbar = document.getElementById("MsgHeadersToolbar");
headerToolbar.minHeight = headerToolbar.boxObject.height;
所以我的實現：
var resizer =
{
is_hidden : 0,
toggleHeader : function(){
if (!resizer.is_hidden){
document.getElementById("headers-box").setAttribute("hidden", "true");
resizer.is_hidden = 1;
}else {
document.getElementById("headers-box").setAttribute("hidden", "false");
resizer.is_hidden = 0;
}
}
}
完事～～ 睡覺
