Can't navigate this site with Firefox, IE8, IE7...
I hope I'm not the only one incredibly frustrated by this new format. I composed a typically well-researched reply to a question only to have the pink-background text "there was an error with your submission. Please try again" unhelpfully appear again and again ad infinitum.
As if that weren't bad enough, whereas in the past Discussions would periodically, automatically save a copy of my reply as a "\draft, this new format doesn't appear to have such a feature, nor can I find a "save" option. So my well-researched and nicely formatted reply is gone.
Next, clicking on a message frequently causes a blank page to be rendered, and clicking Firefox's "back" button won't help since it also renders blank pages all the way back to my Apple Discussions login page. This may be due to this crummy Windows computer I'm using, but again this has never happened before.
Finally, IE8 causes the "do you want only the secure portion of this web page" or such nonsense on each and every page, to the point it's unusable (this has already been reported).
My apologies to those who are waiting for me to reply with help for their problems. They'll have to wait until I can return to my 11 year old iMac running Safari. I trust these new, improved, ultra-secure and needlessly bloated pages will load acceptably fast though.
