As an additional (to all of those who find this via the wrong Google keywords whilst searching) – Here is what the problem is :
If Firefox is common to all the problems then that is most likely the cause.
I’m running 2.51 in a single user environment and my icons to edit the posts are also gone 🙁
The strange thing is that I only have access to viewing the post/page in HTML (I see the <p tags, meaning HTML, but the actual mode selection is on “Visual” and I cant toggle between the two).
I don’t understand how these installations can just fall-over like this.
