Error message

[#1]

The following message keeps popping up on my screen,
We're sorry, there was an error. Description:Component returned failure code: 0x80004005 (NS_ERROR_FAILURE) [nsIStringBundle.formatStringFromName] occurred when we did C24Extension.Overlay.OnDOMContentLoaded
What's the easiest way to repair or stop it. ?
Thanks

that message is on the Firefox forum  https://support.mozilla.com/en-US/forum/1/631919, no answer though

Thanks for that........Makes sense as I have the latest Firefox setup.
I wonder if it is an error with Yahoo or Firefox ?
Perhaps the solution is not to be so quick at updating but equally by not updating I guess you are more open to security risks.
If others have flagged this error up it will no doubt get sorted in time.
Must remember to check future error messages out on Google !!
