User Agent: Mozilla/5.0 (X11; Fedora; Linux x86_64; rv:38.0) Gecko/20100101 Firefox/38.0 Build ID: 20150518065406 Steps to reproduce: Version: 31.7.0 Linux Fedora 20 64bit if you use a remote addressbook url like : http://cal.domain.com/index.php/addressbooks/xxxx@servicename/default/ TB ( or Lightning or Sogo ) does not even try to connect to the server. the same url without the "@" works great: http://cal.domain.com/index.php/addressbooks/xxxx-servicename/default/ It looks like the "@" is misintrepreted as the @ from such an url: "http://user:password@domain/...." which it isn't, as it's clearly in the URI part. Actual results: TB ( or Lightning or Sogo ) does not even try to connect to the server. Expected results: TB ( or Lightning or Sogo ) should work normally, as the same CalDAV url with an @ in the username works as expected.
Please report it to Sogo. Bugs in extensions and such are not tracked in bugzilla.
