I have Firefox version 25.0 and I want to take a screenshot using the following way:
Shift + F2 then screenshot --fullscreen
After that error shows:
Exception... "Failure" nsresult: "0x80004005 (NS_ERROR_FAILURE)" location: "JS frame :: resource:///modules/devtools/BuiltinCommands.jsm :: <TOP_LEVEL> :: line 1764" data: no]
It's not working for my site, but works well for others. I need help. What is the problem?
