I don't know how to get this to the right people, but I found this "bug" and the one it's supposedly a duplicate of via the Google search: ubuntu error "Cannot change to folder because it is not local" ...and I believe it is not a Mozilla Firefox bug, but an OS bug. I'm very new to Linux (XUbuntu), and don't know enough about it to know what the problem might be, but here's my story. The first time I had contact with XUbuntu was on an old 500 MHz machine in Germany. XUbuntu was installed for me and I was on my own. With some playing around, I eventually managed to get Listen Media Player to play streams of my PBS radio station in Hampton Roads. When I got home, I installed XUbuntu on an old machine, and was never able to get it to play radio streams. Eventually, in my attempts to get Listen Media Player to work, I tried "upgrading" it with info from the developers' web site, and that was the end of a functioning Listen Media Player. Even completely uninstalling and reinstalling it doesn't work. I never did try playing a CD with Listen Media Player. Next I tried other media players, and was eventually able to get Rhythmbox to do the job, but it wouldn't play CDs. Then I installed Audacious. I never did find informationon Listen Media Player, but Audacious wasn't any better in that regard; so I have no idea how to even try to get Audacious to play a radio stream. However, when I click the play button, a selection dialog opens inviting me to select a CD track to play. The DVD or CD drive with an Audio CD in it shows up, but when I select that drive, I get the error message: The folder contents could not be displayed Cannot change to folder because it is not local Note that in this case, the CD was in cdrom0, the DVD drive. After that, when I press the play button, neither the DVD nor the CD drive are visible, and the remote file system app (Gigolo) shows cdrom0 as unmounted, Audio Disk as mounted and no cdrom1. If I then click on the Audio Disk in Gigolo, it disappears. If I physically eject the DVD drive with the Audio Disk in it, it and the other drive shown as mounted disappear. It's as if the 2 CD drives are being confused. If I then try to remount cdrom0, I get the following error message: Connecting to "cdrom0" failed. mount: block device /dev/sr0 is write-protected, mounting read-only mount: wrong fs type, bad option, bad superblock on /dev/sr0, missing codepage or helper program, or other error In some cases useful info is found in syslog - try dmesg | tail or so So I tried: dmesg | tail [ 3149.847038] end_request: I/O error, dev sr0, sector 41108 [ 3149.847866] end_request: I/O error, dev sr0, sector 41652 [ 3149.849654] end_request: I/O error, dev sr0, sector 40404 [ 3149.850572] end_request: I/O error, dev sr0, sector 41616 [ 3149.855192] end_request: I/O error, dev sr0, sector 40368 [ 3149.856506] end_request: I/O error, dev sr0, sector 1248 [ 3149.857474] end_request: I/O error, dev sr0, sector 2496 [ 3149.857491] UDF-fs: No partition found (1) [ 3149.866829] end_request: I/O error, dev sr0, sector 64 [ 3149.866861] isofs_fill_super: bread failed, dev=sr0, iso_blknum=16, block=16 Don't come back and tell me there's something wrong with the drive or the CD, I have 2 HDDs in this machine, Windows XP is installed on the other, I have no problem starting either OS, and under Windows XP, both the DVD and the CD drive work just fine...also for playing audio CDs.

different "logical names", it wouldn't surprise me if XUbuntu is confusing drives. I didn't create those names (most are links), the XUbuntu installation created them. So, to me, it's clear that this is either a bug, a problem with the (X)Ubuntu setup/installation CD (which I created from the downloaded image of Jaunty Jackalope, after checking the MD5 sum), or a problem with how the OS installs on this older machine (1.3 GHz Compaq Presario 5410US with 320 MB RAM); it has nothing to do with Firefox (or Audacious. I can access both DVD and CD drive with the Thunar file manager, I can read files on data CDs, and I can boot from XUbuntu, Ubuntu and Mint setup CDs. The confusion appears to occur with audio CDs (haven't tried a DVD, and I haven't tried accessing/playing an audio CD when running off a CD boot of XUbuntu, Ubuntu or Mint). -- ff can't read from an smb share https://bugs.launchpad.net/bugs/24285 You received this bug notification because you are a member of Ubuntu Bugs, which is a direct subscriber. -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
