How do you go back to the old Yahoo email, having signed up (mistakenly) for the new one?

NEW YAHOO! MAIL IS STILL UNSTABLE....IT WOULD BE BEST TO GO BACK TO YOUR PREVIOUS VERSION OF YAHOO! MAIL... To go back to YAHOO! MAIL CLASSIC... Turn off Javascript - you'll then be asked if you want to return to Mail Classic, click "yes". If you don't know how to turn off Javascript... For SAFARI: Open SETTINGS>click PREFERENCES>>click SECURITY>>Uncheck ENABLE JAVA and ENABLE JAVASCRIPT IMPORTANT:Remember to RE-ENABLE JAVA and JAVASCRIPTING back ON when you are back in Mail Classic because without it some mail functions won't work. For IE: Open TOOLS > INTERNET OPTIONS >> SECURITY. In security click "CUSTOM LEVEL" -> disable active scripting in the scripting section. IMPORTANT:Remember to turn JAVASCRIPTING back ON when you are back in Mail Classic because without it some mail functions won't work. For FIREFOX: Open TOOLS -> OPTIONS -> CONTENT, click on "DISABLE JAVASCRIPT". Now hit F5 to refresh the page while you are in Yahoo! email in order to switch back... In the options, click (PERMANENT) to switch back to YAHOO! Classic. DO NOT click the "ONE TIME ONLY" option. IMPORTANT: Turn JAVASCRIPT back ON once you have your "CLASSIC" account back. PLEASE ACKNOWLEDGE IF THIS SOLUTION WORKS BY CLICKING BEST ANSWER..THANKS

You can switch back---as long as it's Classic (which is still available). BUT NOT the "all New Mail" which was the one between Classic and the new version. It no longer exists. Classic will remain an option for those of us currently using it AND who don't want to (or can't) use the Beta version---even tho Yahoo has removed the link to go back to it. (they want to force you to use it) Try this bit of trickery to (quickly and permanently) get back to Classic. Just lower the page "resolution" to the point where it won't support the Beta version. Go to>>your desktop and right click on it>>click on "properties">>click the "settings" tab>>and lower the resolutions>>click OK (and/or "apply"). You "may" then be required to restart your computer. THEN-----Once you've gone back to your mail page ---you will be told that your resolution is too low and asked if you want to switch to Classic as the "default" or "permanently"---(NOT the "one time only"). AFTER changing your mail page back to Classic---- GO BACK and return the page resolution to normal, (so things will continue to work smoothly. ********************************* In Classic you will STILL get the Prompts to upgrade (for a while)---but just click "No Thanks" OR "I want to stay on Classic" (small writing bottom of page). Eventually the prompts will stop (per Yahoo).
