looks like this is a new signature in the RC. 3 crashes on mar9 67 on mar10 156 on mar11 all on build 4.0 2011030319 could be that its morfed from another sig?? users comments indicate: Cannot read PDF files in Firefox 4 Opening an Adobe Acrobat PDF online opened a PDF document using Acrobat X trying to open a PDF document Adobe Reader crashed, but this should not cause Firefox to crash! Add-ons and plugins should be in seperate processes, if they are not already. problem with Adobe reader when opening a document in a new tab i wanted to open a pdf document and the site crashed. Firefox tried to open Adobe Reader to view a document that was printed by Corda. Windows popped up a separate message saying Adobe Reader had a problem open. So, it probably crashed because it didn't handle Adobe Reader's crash.
