One of my friends was talking me about the « auto meta refresh » of some websites like LeMonde.fr, and I was looking for a way to block it. The RefreshBlocker Firefox extension is the perfect tool for it.
But it displays an annoying notification in the header of the pages :
So I made a fork of this extension, to remove the notification : RefreshBlocker 0.8 (« no notifications » version)
(the original add-on is located on its page on the Firefox plugins website)
Some similar plugin exists for Chrome : Stop AutoRefresh
