This is an old version of this issue that might give some insight: *[http://stackoverflow.com/questions/19768144/crystal-report-v10-5-toolbar-not-visible-on-firefox-but-visible-on-ie-and-chrome] also (but I am not sure what version you are using): " CR 10.5 is one of the versions that was not updated to support IIS7." from [http://www.experts-exchange.com/Database/Reporting/Crystal_Reports/Q_28350929.html] It might be ideal to ask a developer in stackoverflow.com or file a bug with webcompat.com for expert investigation for crystal reports. I am sorry I could not be more helpful.
