I was thinking whether editing and altering already cached earlier input strings could be possible. I know that the entire cache could just be deleted using "Clear Recent History". But that is not a well-planned option. Some input strings could have as well been simple typos or ill-formed strings. They could in fact be distractions or eyesores. So why not be allowed an option to edit the cached strings? I always do this for my .bash-history file to keep it compact and useful. So I figure there could be a file in firefox to do just that. Well, for a personal computer dedicated to a single user, this could be a good option.
