The version of firejail in the Ubuntu 18.04 and Mint 19 repositories, 0.9.52, has a few known issues with Firefox. This happened because firefox 60 was released right about the same time we released firejail 0.9.52, and the firefox devs added some stuff in that conflicted with firejail. Later versions of firejail work just fine with firefox.
There are three simple ways to fix this so you can use firejail without issues on Mint 19:
1. Add our PPA and install firejail from it. You'll get the latest firejail and should receive regular updates. I believe this is the best option.
Code: Select all
sudo add-apt-repository ppa:deki/firejail sudo apt-get update sudo apt install firejail firejail-profiles
sudo apt install firejail firejail-profiles, there are three files you should edit:
A) Open /etc/firejail/firefox.profile as root, and replace all the contents with https://raw.githubusercontent.com/netbl ... ox.profile
B) Open /etc/firejail/gedit.profile as root, and replace all the contents with https://raw.githubusercontent.com/netbl ... it.profile
C) Open /etc/firejail/libreoffice.profile as root, and replace all the contents with https://github.com/netblue30/firejail/b ... ce.profile
3. Install the latest release from SourceForge. If you take this route, you'll need to keep an eye out for future releases so you can update manually.
For 64-bit computers, the proper download is currently firejail_0.9.54_1_amd64.deb.
For 32-bit computers, you want firejail_0.9.54_1_i386.deb instead.
