Firefox frequently has problems completely downloading complete web pages. It often takes several clicks of the "save as" button to save more than a few bytes or kb of a web page.
OS is Windows 2000. Problem is with websites in general. Pictures are frequently missing or are blank unless download is attempted more than once. Ads are frequently downloaded as blank.areas. No problems downloading text only sites. PDF file downloads are sometimes stopped.
When web pages are printed using HP software, sometimes the printing is "padded" before and after with blank pages, or the range of pages is incomplete both in the printing review and the printed results. This does not happen when printing from the IE browsers supported by the OS.
