firefox: cannot open file chooser with "Save Page As..."

[Druco]

Description

Just updated to Firefox 133.0 and 'Save Page As...' no longer works.

Steps to Reproduce

1. Start Firefox 133.0 with 'firejail firefox'
2. Open a web page
3. Select File->Save Page As...

Expected behavior

A File Chooser dialog should open

Actual behavior

No File Chooser dialog opens

Behavior without a profile

Firefox works as expected

Additional context

Prior to Firefox v133.0 this was not a problem so it is definitely something that has changed.

I was able to fix the problem by adding:
dbus-user.talk org.freedesktop.portal.*
to my firefox.local file but this may not be the optimal fix.

I tried:
dbus-user.talk org.freedesktop.portal.FileChooser.*
which appeared to me to be the actual interface being used but this did not work.

Environment

• Linux 6.11.8-1-default x86_64
• OpenSuSE Tumbleweed 20211129
• firejail v 0.9.72

Checklist

• The issues is caused by firejail (i.e. running the program by path (e.g. /usr/bin/vlc) "fixes" it).
• I can reproduce the issue without custom modifications (e.g. globals.local).
• The program has a profile. (If not, request one in https://github.com/netblue30/firejail/issues/1139)
• The profile (and redirect profile if exists) hasn't already been fixed upstream.
• I have performed a short search for similar issues (to avoid opening a duplicate).
  • I'm aware of browser-allow-drm yes/browser-disable-u2f no in firejail.config to allow DRM/U2F in browsers.
• I used --profile=PROFILENAME to set the right profile. (Only relevant for AppImages)

dbus-user.talk org.freedesktop.portal.FileChooser.*

The name should be org.freedesktop.portal.Documents which is already allowed in firefox-common.profile to fix drag and drop under some(?) systems. So this issue can likely be closed as an duplicate.

Thanks for the quick reply.

I found that adding just "org.freedesktop.portal.Documents" did not work. After some more debug, I found that it also required "org.freedesktop.portal.Desktop" to be included, which is commented in firefox-common.profile to indicate that it is needed for "sceensharing under Wayland", so perhaps the comment could be changed to say that it may also be needed for file saving to work under FF133.

Does it work with firejail-git?

Also can you try the following and post the result?

• firefox: cannot drag and drop files from Dolphin #6444 (comment)

I pulled master from github and that version does not work out of the box. I have attached four files, two with the output from the comment you listed and two from when I ran with the command '/usr/local/bin/firejail --dbus-user=filter --dbus-user.log --dbus-log=xxx.dbus firefox'.

The two that have 'noDesktop' in the name are run from the git firejail as is, and the file chooser popup never came up. The two that have 'withDesktop' in the name were run with the line "dbus-user.talk org.freedesktop.portal.Desktop" added to my 'firefox.local' file and worked as expected
NoDesktop.dbus.txt
WithDesktop.dbus.txt
busctl_noDesktop.txt
busctl_withDesktop.txt
