When using the search function in history on FF Mobile, the option to delete individual history items is not available. Being able to bulk delete just the search results would also be nice to have.
This is not only helpful for bulk deletions but also for deleting (ancient) history items that might be responsible for an annoying URL completion when only discovering that annoyance much later after the the site has been visited. Currently, it is next to impossible to find the "offending" URLs in a large history stack by scrolling, such that the X could be used to remove them, which only leaves one with the option to delete the whole history and lose all actually desired completion suggestions along with it.
