I am not one who frequently blegs here. But.
Suppose that, like me, you are an astoundingly bad typist. And suppose that, like me, from time to time, despite nice tools like the autofill plugin, sometimes you mis-enter something into a web form. Like, say, your email address without the final “u”.
And suppose that Firefox remembers this for all time and puts it in alphabetical order above your real address. And suppose further that the little bitty box into which you are suppose to enter an email address is too short to see that the final letter is missing, so you have to remember. And suppose further that you often don't.
In such a case, you would dearly like to edit firefox's list of recalled dropdown entries…without deleting them all and starting over.
Where do they live? Can this be done?
