There is a glitch sometimes with the newspapers on there which makes them blurry when downloading for some reason. I have found that when saving a clip, including the full page, if the file name is 'default' then it will not save properly.
If this happens, then duplicate tab (by right clicking on the top of the open tab and choosing 'Duplicate Tab') and refresh or go back to search results and go back into the newspaper image again and the file clip should save clearly with the name and date of the newspaper as the file save name.
