I don't think this is possible in an browser add on feature since it's implementation would be considered to be cross site scripting, which is not allowed.

any possible way to implement 1-click snipes? right now the fastest method requires 3 clicks. 1 to open the gixen add-on. 1 to click into the amount field. and 1 click to add the snipe.
