為了等待某個詞的出現，我讓一個討論區，請一個外掛，不停地、不停地重讀。
假如能夠 find 到那個詞時，發出聲音通知我，
我就可以同時做別的事了。
DOMContentLoaded&gBrowser.contentWindow.find('WORD_I_CARE')
（事件類型是 window event）
每次 DOM 讀完後，便自動進行尋找（Ctrl + F），若有找到就發出聲音。
實際上要加入網址限制，免得每個網站都自動尋找：
DOMContentLoaded&(event.target.location.host==='www.forum.com'&&gBrowser.contentWindow.find('WORD_I_CARE'))
除了 host，也有其他屬性可用來設限制，參考 window.location (#properties) - MDC Doc Center。

雨傘魔鬼氈不黏修理 2018-03-15 Yeah it really works but its better to keep a towel or any kind of cloth below the stained cloth nor the stain will be absorbed by the other side of that cloth.And it really doesn't matter whether the stain is of 1 week or 1 month.
雨傘魔鬼氈不黏修理 2018-01-25 Alec is awesome! I fix nearly everything that I possibly can in my home and use youtube almost exclusively. Most posts are a constant ramble and yammering and words filling dead air space. It 's unnecessary and confusing. Alec speaks only when necessary and demonstrates each fix quickly and accurately. Camera person is completely tuned in to every move Alec makes. Thanks! Just spot on
