According to this post http://en.forums.wordpress.com/topic/new-post-editor-improvements?replies=5
The next time you select to use the classic editor instead of the new editor, we'll remember it! From then on you'll be directed back to the classic view instead, you won't have to select it every time.
I have select the classic editor MILLIONS OF TIMES, and wordpress still don't remembers my decision. When I try to create a new post from the wordpress top bar on my blog I am redirected to the new editor not the old one. Same goes to editing articles from the front page.
This is extremely annoying and frustrating.
Using Firefox 31.0
The blog I need help with is strangera.com.
