i hate yahoo mail beta

so, i go to check my yahoo mail this morning and see something yahoo mail beta. "wtf?" says me. and it logs me in. and my screen is now showing the fecking ugliest screen i have ever seen. it looks like the mail system in MS Outlook or AOL...i used yahoo because it was different than that. before, i could go through and open the emails i wanted to read in tabs and quickly scan one after another (thank you firefox). *now* i have to go back to the stupid old system of a new window for each. i *hate* that.

does anyone know of how to revert? or change a setting to get back? this new system blows like a starving brooklyn hooker.

*edit*
and now i see the "switch back" feature. -_-

oh well. who else hates this freaking ugly new system?
