is there any way to disable?

Hi, I've an RSS feed with xsl and with Firefox I've the read mode button in this page. Anyway, when I click seem to go in read mode, but reload to full release after seconds. If there is any way to deny read mode, maybe can be useful. Also, I've another page with similar content, without read mode button. A doc (or a JS, or a metatag) to allow or prevent read mode will be very useful. Ty.
