I now have at least two (probably more) sites (one on 1.1.2, one on 1.1.3) where I can't do in-line edits. When I click the link to edit a post, the text flashes in the Tiny MCE window & disappears. I have to go to "more options" or open the editor in a new tab/window to edit. This started a few minutes ago & immediately after I allowed Firefox to upgrade to 23.0. Most unlikely a XenForo bug so not reporting there -- these forums have been running just fine for many, many months. Edited to add: Also happens on 1.1.4. Not happening on my 1.2.x (still beta) sites nor here on "xenforo.com".
