Based on your indication that the listed extensions were compatible w/ Thunderbird 6, I installed:
-- Thunderbird 6 -- Webmail 1.4.2 -- Webmail Yahoo 1.5.3 Upon restart, my 3 Yahoo POP accounts: -- displayed: Sending of password did not succeed, Mailserver localhost responded: that's cool -- Clicked OK -- displayed: Login to localhost failed. Retry and Enter New Password did not resolve issue. Had to hit Cancel for each "Login to localhost failed" pop-up to stop endless loop. Thunderbird 5, Webmail 1-4-0a1, and Webmail Yahoo yahoo-1-5-0 worked fine before these changes. Really don't want to go backwards. Any suggestions?
