Thank you for this - it's very timely
I do have my password saved and use Firefox but have experienced no problems posting to communtities. I do, however, have the choosing an icon problem when posting to my own IJ. This is a fairly recent 'bug' for me and I get round it by posting an entry and immediately edit it. But then, even though I can choose an icon for the entry, it will neither display nor allow me to browse my icons while in edit mode.
