This can happen for example on Flash website, like YouTube. $ ps aux | grep firefox foobar 6630 3.6 2.0 198764 70408 ? Sl 13:27 0:06 /usr/lib/firefox-3.0b5/firefox foobar 6721 7.7 0.8 93496 29548 ? Sl 13:30 0:00 /usr/lib/firefox-3.0b5/firefox foobar 6728 0.0 0.0 3008 768 pts/0 R+ 13:30 0:00 grep firefox
Then I click on the OK button on the "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." dialog. $ ps aux | grep firefox foobar 6630 3.3 2.0 198764 70408 ? Sl 13:27 0:06 /usr/lib/firefox-3.0b5/firefox foobar 6732 0.0 0.0 3008 772 pts/0 R+ 13:31 0:00 grep firefox So this means Firefox is running in the background even if I close it... -- 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
