Sadly saving files to my home directory or $HOME/Downloads does not work at all, because firefox does not even open the corresponding context menus. All actions where firefox seems to have to read, write or execute files are not working:
Right click on page -> Save page as -> Nothing happens, i.e. context menu for saving action does not open Right click on image -> Save image as -> Nothing happens Print -> Save as PDF -> Save -> Nothing happens Open page with zoom invitation -> Left click on "Launch meeting" -> Nothing happens Open drive.google.com -> New -> File upload -> Nothing happens Uploads to other pages do not work either However what opening href links to PDF files which are directly downloaded to $HOME/Downloads and then displayed with the build in viewer works fine. So I guess that not the file access per se, but some dbus action for opening the context menu is blocked by apparmor. This is also the dmesg excerpt suggest, which I attached when filing the report. For the time being, running firefox outside the snap confinement works just fine for me. -- You received this bug notification because you are a member of Desktop Packages, which is subscribed to firefox in Ubuntu. https://bugs.launchpad.net/bugs/2042543 Title: Firefox-snap cannot save files or launch apps due to faulty apparmor configuration Status in firefox package in Ubuntu: Incomplete Bug description: Since a recent update, firefox cannot any more save pages, images or download files. It also cannot launch other processes like zoom via meeting links. This seems to be caused by a faulty apparmor configuration and a common problem since the introduction of the snap package, e.g. c.f. https://arstechnica.com/civis/threads/snap-based- firefox-is-a-terrible-experience.1487499 or https://ubuntuforums.org/showthread.php?t=2476758 . However, none of the proposed workarounds works for me, neither editing apparmor configuration files, reinstalling firefox, or refreshing it via Help -> More troubleshoot information -> Refresh firefox. Finally, I found that snap installs two binaries, one in /usr/bin/firefox and one in /snap/firefox/3252/usr/lib/firefox/firefox. If I start firefox from cli with typing firefox, the first one is invoked, which is broken. If I explicitly invoke /snap/firefox/3252/usr/lib/firefox/firefox, saving works fine. So I just aliased the second binary to firefox in the .bashrc. This binary also strangely seems to use its own configuration, i.e. own apps, password storage, etc. I hope this information helps other users with the same problem and the package maintainers with fixing the configuration.
