If you’ve recently encountered issues like strange page redirections and vanishing data with Wordpress when entering or editing posts, then you may be a  victim to a bug in Firebug. That’s what’s hit me.

I just upgraded to Firebug 1.4 and now when I use Firefox and go into my Wordpress to create a new post, the screen redirects to a new page with just the formatting buttons and tabs at the top, and the page never seems to stop loading.

And it’s happening on several installations across different sites. Argh!

Turns out it is an issue with Firebug and or Firefox. The fix for me was upgrading to the latest version 3.5.
