Since updating Firefox browser, i am unable to gain access to my yahoo email account. I can access the email with Interent Explorer with no trouble. Whenever I click on a mail link on the yahoo sites to check my mail, I get rerouted to an error page ..... "Sorry, we can't find "ca.mg4.mail.yahoo.com/dc/launch?.gx=1". Please check the spelling of the web address." is what is said at top of page whenever I click on any mail links.
