Public bug reported: When talking to an hostname consisting of a single letter, Firefox 3.6.18 does not set cookie. Previous version did fine, as well as other browser such as chromium.
How to reproduce: sudo apt-get install lighttpd sudo lighttpd-enable-mod cgi sudo vim /etc/hosts make 'a' go to 127.0.0.1 as in: root@machine:/var/www# head -n1 /etc/hosts 127.0.0.1 localhost a Then simply install the attached python cgi and go to it in firefox-3.6.18. In our tests it never set a cookie. When testing with Chrome, it sets the cookie fine. root@machine:/var/www# lsb_release -rd Description: Ubuntu 10.04.2 LTS Release: 10.04 root@machine:/var/www# apt-cache policy firefox firefox: Installed: 3.6.18+build2+nobinonly-0ubuntu0.10.04.1 Candidate: 3.6.18+build2+nobinonly-0ubuntu0.10.04.1 Version table: I expected my cgi script to print something like: The returned cookie string was "foo=1308946645.14" and not: First visit or cookies disabled. ** Affects: firefox (Ubuntu) Importance: Undecided Status: New -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/801778 Title: Regression: Firefox 3.6.18 do not set cookie when talking to single letter hostname To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/firefox/+bug/801778/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
