"If you get this error while viewing a webpage, it means a plugin has crashed. You can send a crash report to Mozilla by clicking on Send crash report. " but why do I not get the button "Send crash report"?
This is the most recent upgrade to my Firefox version 3.6.8 Mozilla Firefox for Ubuntu canonical - 1.0 Mozilla/5.0 (X11; U; Linux i686; en-US; rv:220.127.116.11) Gecko/20100723 Ubuntu/10.04 (lucid) Firefox/3.6.8
Since then, every web page that makes use of the Adobe Flash plugin shows me grey windows with the message "Adobe Flash plugin has crashed".
When I follow links telling me I can find out more I am taken to a Firefox Help page that shows an example of the same grey window with the same message. But there is a difference: directly under the "Adobe Flash plugin has crashed" message is shown a another message that says: "Send crash report". The Help page instructs me to click on that message because it is intended to be a link.
Unfortunately, on all the grey windows displayed to me on any site where this problem arises, no such message: "Send crash report" is present. So how can I send a crash report?!
You have the Ubuntu-specific build of Firefox - released as a package in the Ubuntu repository - and that has been built without including the crash reporter.
(So-called 'contributed builds' usually lack the updater - in the help menu - too, because they have their own updater.)
