Over the years here have noticed that I cannot really complete any blocks with pictures as it keeps going to the security authentication and doesn't post such that I do not post any blogs lately.
I have now noticed too that Firefox is doing more security now that before.
A couple of days ago ran in to an issue updating a profile on an account. I could not using Firefox and had to go to Windows Explorer to complete the update.
This morning noticed the following error when trying to update one blog.
ERROR for site owner:
Invalid domain for site key
