New in version

January 9th, 2014
  • Yahoo disabled SSL access to, so now any attempt to read returns a 404 error, which breaks checking for new mail. I have no idea why this was changed, but as a result, the addon will no longer use SSL when performing the new mail check. This is simply grabbing the number of new emails so it's not terrible that SSL can't be used. As always logging in always uses SSL.

New in version (December 17th, 2013)

  • Add work around for invalid Yahoo SSL certificate. For some reason sometimes Yahoo doesn't use a correct certificate for, so in that case revert back to non-SSL in that case. I'm not sure what the pattern is here because sometime the certificate shows as being valid and other times not. None of the fetched data from the Yahoo home page is considered private with the possible exception of the number of new messages (the messages themselves are not fetched), so reverting to non-SSL doesn't really cause a loss of privacy or security. Logging in is still always done via SSL.
  • Changes to make more compatible with Firefox 28 and up.

  • still didn't work for Yahoo users in certain countries. I came up with a method that should work for everyone. As such I removed the alternate check option. If you still have problems, enable logging by changing the "extensions.ym_notifier.logenable" preference in about:config to true and send me all three log files after checking for mail.
  • In addition I now use SSL when checking for new mail since it is now supported by Yahoo.

  • 1.0.7 didn't work for Yahoo users in certain countries because Yahoo is currently using two different server configurations which are not entirely compatible. This should now be fixed. I added a "alternate checking method" to force switching between the two methods, so if checking doesn't work, try checking that box in the preferences. If it still doesn't work, clear the "" cookies from the browser and log in to Yahoo again.
