totalement incapable de modifier un header de réponse

Doesn't work sometimes.

At random intervals, this extension stops doing the one thing it's designed to do: inject headers in browser requests. There is really no consistency to this, I had to simply disable the extension and use another.
Since this one has URL filtering(and the other one doesn't) I'm still leaving this as installed. Otherwise, there's no real reason for me to keep this. Consistency is vital.
