Steps to reproduce:

  1. I'm using Ubuntu 22.04
  2. I mounted internal hard disk to /mnt folder
  3. Firefox snap connection to removable-media is done.
  4. I started latest firefox snap.
  5. When I try to download file or save page to hard disks mounted to /mnt download process doesn't start.
  6. However download to /media works as expected.
  7. Moreover another snap GIMP saves files to /mnt.

Actual results:

  1. Download process doesn't start
  2. There are not information about this download in download history
  3. There are not new files in destination directory

Expected results:

Download process should displays the progress bar. Firefox should display this download in history. And file should be saved in subdirectory in /mnt path.

Can you check whether there are apparmor denials reported in the system journal when the problem happens?

How do you mount to /mnt ? I'd guess it's not via something that removable-media expects, and this is why you dont have access ? Usually, drives mounted via gvfs are under /media as much as I can remember.

Flags: needinfo?(pnck)

I'm having the same issue. Reported here: https://bugzilla.mozilla.org/show_bug.cgi?id=1773510

Andrey, can you repro on current versions as well? If you do, we could welcome a about:support as well as /usr/libexec/xdg-desktop-portal -rv and journalctl -f while reproducing.

Please attach about:support on the bug, not a third-party website

I dont see any SaveFile in the xdg-desktop-portal log shared, did you reproduce the issue when capturing it ?

Alexandre, I'm sorry, this message have been written by mistake. Bugzilla portal also has some bugs, something about s3 access.

After couple of updates the issue with firefox does not exist now. And I can download files to any location in /mnt.

We can close this bug i think. Because i can't reproduce it now.

For the about:support ? Weird, you should be able to attach it

Perfect, thanks for taking the time to verify!
