I use Imacros. I got this error NS_ERROR_UNEXPECTED: Component returned failure code: 0x8000ffff (NS_ERROR_UNEXPECTED) [nsIPrefBranch.getCharPref], line 3 (Error code: -1001). I think it is because of this version of mozilla firefox 28.0. I read I should downgrade the version to 27, but I have read it is not safety. Will the problem will be resolve? if not I think I should take the risk...
