Sorry, I forget to say, that normally the correct behaviour is, that in the Add-Ons -> Themes section a button is grey on a theme, which is selected currently. But human theme is not selected automatically when having installed firefox-themes-ubuntu. Firefox default themes seems to be selected and it looks like this.
OK, let's conclude: So on Firefox default theme, the button is grey, you can't activate it, which is right, because it's running. But I wonder, why the Human theme, which is _not_ running at this time, can not be selected, either. While selecting Tango oder Tangerine works in first run. Human only with workaround, described above. This is a more essential despripton. I hope you can get it or reproduce this behaviour? When I got time I can make some screenshots, if they are necessary. -- Human theme appears in Add-Ons but can not be selected - others (Tangerine etc) working https://bugs.launchpad.net/bugs/139517 You received this bug notification because you are a member of Ubuntu Bugs, which is the bug contact for Ubuntu. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
