Yup that was it. That's annoying, that is not the first time an auto-update has added layers of settings that have affected my browsing abilities in firefox. (another one I can think of was the annoying re-direct warning).
Indeed the network.http.sendRefererHeader was set as 0
I typed about:config in my firfox address bar and was able to change that option to 2 (as integer) after scrolling and finding it.
I would not have ever guessed that!! But now will keep an eye out. BTW- Would this affect registered users as well? Or only admin functions?
thanks again.!!
This was definitely part of a presumed major problem we have been having. And we are cleaning up our files in the process, too. ;)
