Here is the situation. I typically want Firefox to block redirection, as most of the time such redirection is evil. However, there are some cases in which the redirection is fine. I don't know if this is just poor website design, but I have a financial institution that does a redirection for certain features, and sometimes I don't notice the bar at the top that is telling me to allow redirection, and it takes me a while of pulling out my hair to figure out why it is doesn't work. Evidently, Firefox takes the attitude to give only an all or nothing choice for this warning. I was hoping that some enterprising developer has developed an add-on that does something like popping up a dialog window saying "The website foo.com is attempting to redirect to bar.com. Do you wish to add this to the list to block, add this to the list to allow automatically (i.e., which will suppress this dialog), or do you wish to block or allow this without adding to any list?" Is there an add-on that does something like this?
