When copying data from a site which contains a long list (= one requiring scrolling down), any list item which references a large jpg file causes the site to reset to its top when editing of that file is completed. Firefox should have an option which holds a long-list file at the item most recently edited or copied. It is bothersome and unnecessary to keep scrolling down a long list every time a complex copy or edit is performed. Example: https://species.wikimedia.org/wiki/Charaxes is a typical long list. See the figure for Charaxes boueti, for an example of a figure which, when copied as a jpg, causes the list to reset to its top. If an edit option is not added, at least ALL edits of a long list should keep the edit location displayed. Currently, this holds only for editing of simple images, not complex, multi-item images requiring jpg formatting.
