リンク先のファイルの種類によってマウスカーソルを変える
（12/14に書き直しました。以前の内容は念のため id:mitamu:20051214#1134571263 にとっておきました。ご迷惑をおかけしてたいへん申し訳ございません。）
WebページのリンクをクリックしたらそれがPDF文書だったりWord文書だったりExcelワークシートだったりして、ファッキン*1なAdobe ReaderとかMicrosoft WordとかMicrosoft Excelとかが起動してしまった…。
なんてコトがよくあるわたしとしては、PDF文書だとかがはっきりわかればそもそもクリックせずにすむワケなのだ。
Mozilla Firefox 1.5だとマウスカーソルを変えられるので、userContent.cssにごにょごにょと書いてあげるとよかったりするってのをさっき確認した。
なお、拡張機能としてはTargetAlertというのがあります。教えていただいたみなさま、ありがとうございます。
さてさて、やりかたメモ。プロファイルディレクトリを "[ProfD]" と表すコトにします。
1. マウスカーソルの画像を用意する
まずは、マウスカーソルの画像を用意します。わたしはfamfamfam.com: Silk Iconsにあるアイコンを利用してこんなのを作成してみました*2。
3. [ProfD]/chrome/userContent.cssにごにょごにょと書いてあげる
最後に、 "[ProfD]/chrome/userContent.css" というファイルを作成し、次のような内容にします。
@charset "UTF-8";
/*
* [ProfD]/chrome/userContent.css
*/
/* cursor: url(data:MIMEタイプ;base64,符号化した画像),pointer; みたいに書く */
