Original GitHub issue: https://github.com/netblue30/firejail/issues/6267

Description

Chromium does not preserve cookies, sessions.

Steps to Reproduce

  1. Run in bash LC_ALL=C firejail --private=/tmp/work --ignore=private-cache --profile=chromium chromium
  2. Login to any service/website of your choice
  3. Check cookies (F12 -> Application -> Cookie/Session storage)
  4. Close browser
  5. Run 1. again
  6. Open website again
  7. See that you're not logged in anymore (and you probably get cookie banners again)
  8. Check previous session cookies are gone (F12 -> Application -> Cookie/Session storage)

Expected behavior

Cookies (and thus sesssions) should be preserved.

Actual behavior

Cookies (and thus sessions) get lost.

Behavior without a profile

Same.

Additional context

None.

Environment

  • Linux distribution and version: Arch Linux
  • Firejail version (firejail --version): 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)

So permanent cookies get lost when restarting with --private=<dir> but other stuff like bookmarks are preserved, right?

Yes, correct. Bookmarks, settings, history are all fine. Even the cache gets preserved (with --ignore=private-cache).

Oof, I had Clear cookies on close turned on per default... classic PEBCAK. Sorry for the noise!
