I have a paid subscription to Ancestry.com. I have the [http://ancestry.custhelp.com/cgi-bin/ancestry.cfg/php/enduser/sab_answer.php?p_faqid=3118&p_search_text=firefox%20enhanced%20inage%20viewer&p_created=1191944594&p_sid=fjDx*drk&p_accessibility=&p_redirect=&p_lva=&p_sp=cF9zcmNoPTEmcF9zb3J0X2J5PSZwX2dyaWRzb3J0PSZwX3Byb2RzPSZwX2NhdHM9JnBfcHY9JnBfY3Y9JnBfcGFnZT0x&p_li=&p_topview=1 Ancestry Enhanced Image Viewer] that was working fine in Firefox 3.x (the last version of 3). Now in version 4 of Firefox, the viewer locks up Firefox 4. The window that opens to save the image to your computer comes up, but then Firefox 'freezes' and won't allow me to enter a filename to save the image. I have to use 'cntl-alt-del' to shut down Firefox. I have to go to IE8 to get the image. A similar problem is happening with my PDF statements from my bank opening in a separate window to view or safe. Worked fine in Firefox 3.x, does not work at all in Firefox 4. (I and others have reported this.) I have to use IE8 for that task also. Really annoying since any site that uses PDFs in a new window (for instance, [http://www.sos.mo.gov/archives/resources/deathcertificates/Results.asp?type=basic&tLName=crigler&tFName=&sCounty=all&tYear=#searchdeat Missouri Death Records PDFs] ) will not work. I am using the current Adobe Reader X which used to work in Firefox 3.x. I HATE having to use IE8, but Firefox 4 does not seem to be ready for 'prime time.' And you're going to push out Firefox 5 in June!??! Slow down and fix what ya broke first. Thanks, Sandy
