Win 7 Ultimate SP1
NIS 20.3.1.22
Firefox 21.0
I get intermittent error messages in Firefox when I click on a thread link in the forum. See below.
I was also unable to directly upload the image from my computer using the tree icon on the message toolbar.
I have restarted Firefox and my computer and still get this problem.
IE does not seem to be affected.
Is there some setting in Firefox that has changed over the last month or so?
