Hi Lars! Yes, I updated Firefox last week and I discovered that it will no longer open my many pages that I have saved in HTML. However I found that I can open them all in Safari without any problems, so far. I use the right mouse button and I point it to the HTML file and when the menu drops down I click on the OPEN WITH... And I open it with Safari. I feel that Mozilla will repair this problem because I suspect that many people save material in this manner. Bill Montreal
