For some time now using the "attach screenshot" applet crashes Firefox, the crash happens as soon as I click the menu option. I'm using JIRA (v5.1.8) Java SE 7 U21 10.21.2.11 plugin. Firefox 21.

Using IE 10 i can get to the attach screenshot page but when I try to attach it says "Java Platform SE 7 U21 has crashed). (this could have been before I pasted not sure)

Using Chrome it's like IE but before I paste.
