I have a numbers sheet which suddenly turned up as a thumbnails.jpeg which I can see is a spreadsheet but too tiny to view. How can I open it in its original size and how did this migrate to a firefox doc app?

I have a MAC OSX10.6.8. I use Apple's numbers program to do spreadsheets. I have a spreadsheet which I have worked on intermittently for 3 years. The last time I closed it in Sept 2011. it was ok. When I reopened it again in Nov it had become a "Thumbnail.jpeg (240x310 pixels.) " I can see that it is the spreadsheet, but I can not enlarge it so that it is useful. It is just a blurred image. I have no idea how this happened. When I click on it, firefox opens so I believe that it is a Firefox app. Info from Firefox: Render mode: Quirks mode Encoding: ISO-8859-1 Modified Sept 22, 2011 3:19 pm
