UCSS reload usercss
userContent.css と userChrome.css(以下 usercss)を @import を使って管理するための補助スクリプト。
usercss や @import で読み込まれた .css のリロードや編集が可能。
どうしても Stylish を使いたくない ucjs 信者か、ローカルの .css を利用したい人向け。
思いつきで作ってみたものの、これ以上作りこむ気にならないのでここに放置。

◆ これは何? ◆
userContent.css と userChrome.css(以下 usercss)を @import を使って管理するための補助スクリプト。
usercss や @import で読み込まれた .css のリロードや編集が可能。
どうしても Stylish を使いたくない ucjs 信者か、ローカルの .css を利用したい人向け。
◆ 使い方 ◆
usercss に :root{} と記述しておく。
.css の編集機能はスクラッチパッドを利用。
Ctrl+S で保存と同時に CSS がリロードされる。
■メモ
chrome の再描画は一度背面にする。
content は markup を利用。背面のタブの内容が再描画されないのはご愛嬌。
usercss の @import は insertRule, deleteRule しても効果がない
 insertRule は loadText + parseStyleSheet で対処
 deleteRule は disabled + リフレッシュで対処
usercss をリロードしても @import はリロードされず無効化される
 CSSImportRule.styleSheet はあるが cssRules が 0 個
 @import の追加・削除をチェックして自前でロードすることで対処
usercss を再読込すると @import 内の XBL がセキュリティエラーになる
 セキュリティエラー: moz-nullprincipal:{...} のコンテンツが file:///.../xbl.xml#id を読み込みまたはリンクすることは禁止されています。
  usercss > import > XBL←これがNG
  usercss > import > import が起動時ですら実行されてなかったorz
 ※対処法 - XBL は usercss 本体に書く
■今後
CSSEdit 関数は要改善
UI を考える
やる気が出ないので当分放置かも
