More specific: "Firefox prevented this page from automatically redirecting to another page" and the only option I have is "Allow".

Do I have an option to see the page to which I am being redirected before I allow it?

What if a virus is doing redirecting? What if it is a legitimate redirection? What if the redirection is to a hazardous/dangerous page? Why all the mystery?

How I delete an accidental reply? (like this one?)

Hello Emerogork, try the next add-on : Redirect Bypasser

How I delete an accidental reply? = you can not ! only moderators can do that.

thank you

Note that the setting in "Options > Advanced > General" is meant as an accessibility feature, as you can see by the label of that section, so that people with disabilities or people who use screen readers do not get confused and is not meant as a safety protection to stop redirecting.

• Firefox > Options/Preferences > Advanced > General : Accessibility : [ ] "Warn me when web sites try to redirect or reload the page"

I already had that set, hence my question.

Since Firefox "realizes" that a redirection is about to happen, would it ot be prudent to let me know what the new site is going to be?

This is like saying "One of the turns ahead is about to take you into oblivion, do you wish to take of them?
