Hi I discovered a Linux Sandboxie alternative about half a year ago and just recently I started using it's called Firejail and while I'm not an advanced user I still get some use out of it and frankly I just feel safer using it. Firejail is fairly easy to install and use, to sandbox Firefox you just enter firejail firefox in the terminal and there are other FJ profiles as well such as private mode https://l3net.wordpress.com/2015/02/19/firejail-a-security-sandbox-for-mozilla-firefox-part-2/ which creates a temporary clean browser profile and deletes the contents after your done which is ideal when testing add-ons. You can also create your Firejail own profiles like private-keep which copies your browser profile and deletes the contents after your finished but I don't know how to do this.
Here's a video I found about Firejail:
I hope everyone finds this useful and I hope it will help keep all of you malware free.
