I have a Wordpress.org blog. In the past few months, Firefox has developed a conflict with my site. I can no longer save posts in draft or publish mode. Similarly, it will not autosave or save a post revision. When I try to do so, the homepage displays instead of the post edit page. Also, when I try to use the WP image functionality I can upload the image to my server, but it fails to insert it into the post edit box. I ''can ''''''manually insert the code and the image will display. Troubleshoot mode, clearing the cache did not work. But I could perform all these functions in private mode. I can't figure out whether this is a browser issue or a WP issue or a conflict between the two. I have none of these problems in Chrome.
