Thank you for reporting the bug. I tried to reproduce it (configuration below) and was able to successfully set the desktop background by clicking on the popup (as you had described). Could you please provide further details?
I think that the popup is part of Ubuntu and firefox is only invoking the program. Try to save the image file and use the change desktop of Ubuntu (Right click on desktop and change desktop background and choose the downloaded image file). Please let me know if this works. lsb_release -a Distributor ID: Ubuntu Description: Ubuntu 9.04 Release: 9.04 Codename: jaunty ra...@raghu-desktop:~/mozilla/browser/app/profile$ apt-cache policy firefox firefox: Installed: 3.0.10+nobinonly-0ubuntu0.9.04.1 Candidate: 3.0.10+nobinonly-0ubuntu0.9.04.1 Version table: *** 3.0.10+nobinonly-0ubuntu0.9.04.1 0 500 http://archive.ubuntu.com jaunty-updates/main Packages 500 http://archive.ubuntu.com jaunty-security/main Packages 100 /var/lib/dpkg/status 3.0.8+nobinonly-0ubuntu3 0 500 http://archive.ubuntu.com jaunty/main Packages -- "Set As Background" pop-up doesn't work https://bugs.launchpad.net/bugs/369074 You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
