I think this is a bug. When this occurs, I have closed Firefox, it is not visible on the screen, but for some reason it is still running something in the background.
Every time I click on the Firefox launcher icon, it says "Firefox is already running, but is not responding. To open a new window, you must first close the existing Firefox process, or restart your system." This makes it impossible to surf the web, since I cannot open a web browser. A clueless noob would have no choice but to restart this computer. Clever as I am, I discovered a "work-around" by doing "killall firefox", but people shouldn't need todo this. ** Changed in: firefox (Ubuntu) Status: Invalid => New -- Firefox is already running, but is not responding... https://bugs.launchpad.net/bugs/232005 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
