Securing the Firefox Web Browser whilst surfing the net, using a Sandbox Programme Called "Firejail" along with "Firetools" that also gives the programme a decent GUI.



Also, Linux Sandboxing another application


Bare in mind...................I'm using this Sandboxed environment in Linux (Mint) here, but it should work in Debian, Ubuntu, Mint, Fedora, OpenSUSE, Centos, RHEL.

So....
The packages I installed were both amd64.deb (Debian) and were easy to apply without compiling. You may have to search around yourselves for a compatible version (hey this is Linux not Windows).

Web Comments

Now days security threats are everywhere in the web, new security holes are discovered everyday, but sadly there are no instant patches available. If you are a firefox user, this problem is worse, as it lacks the sandbox feature like chromium or google-chrome browser.

Here’s how to protect yourself from such threats by running Firefox in Sandbox environment with Firejail.

What is Firejail ? ?



Well.......Firejail is an extremely lightweight Linux namespace based Sandbox application, could be used with both GUI and CLI applications with minimal effort.

It could effectively run most apps with limited permission and system resource to minimize security risk. There’s also a GUI app firetools , to launch and monitor apps with Firejail.

Installing Firejail and Firetools......................

Firejail is already in Debian testing and Ubuntu 15.10 (Wily Werewolf) official repository, there are also binary deb and rpm packages available at sourceforge. Download the relevant binary package from this sourceforge repository ( http://sourceforge.net/projects/firejai ... /firejail/ ) install it with your package manager.

For Debian based systems, use this command
sudo dpkg -i firejail_0.9.30_1_amd64.deb

Now download the relevant firetools package from here and install it. Firetools requires basic Qt4 or Qt5 application runtime libraries, make sure they are installed too.
sudo dpkg -i firetools_0.9.30_1_amd64.deb

Firetools is optional, but it is easy to launch applications and monitor them with firejail.

You could also install firejail in Debian testing and Ubuntu 15.10 straight from the official repository.
sudo apt-get install firejail

Firetools is the graphical user interface component of Firejail.

Firejail is a SUID sandbox program that reduces the risk of security breaches by restricting the running environment of untrusted applications using Linux namespaces, Linux capabilities and seccomp-bpf.

Start firefox in sanadbox environment with Firejail

Now It’s the time to run firefox in sandbox environment, first we are going to do this with command line,
firejail firefox
in a Terminal or, it should be in Menu where you can just click to launch it.

BTW Just this ! Make sure that no other previous Firefox instances are running already. In caseit is, use this command
firejail firefox --new-instance
in the Terminal Window.

Some advanced Firejail sandbox commands are:

Start Firefox in a seccomp sandbox environment
firejail --seccomp firefox
Start Firefox in a Linux capabilities sandbox environment
firejail --caps firefox
Start a Firefox with a new tmpfs private home directory
firejail --private firefox
List all running sandboxes
firejail --list
Print a tree of all sandboxed processes
firejail --tree

Launching and monitoring Sandboxed Firefox or other apps with firetools................

(Firetools is the GUI app for monitoring and launching other apps in the sandbox environment, just find the Firetools launcher icon and Launch it. This will most likely be in Menu; All Applications>Firetools)


In Action..........Check with Terminal Command, as stated above: firejail --list


When you close Firejail down the session is now unprotected once again.

Further edit...............................................

Configure for use.....Right Click the Firefox Icon and select Edit. Give it a title and use the wording listed in the boxes below it, as screen shot


From then on you can see the activity of CPU usage etc from the Tools and Stats Sandbox List



I know this is not Sandboxie, but this is going somewhere when Linux users and scripters are pricking up their ears, regarding today’s security issues.
It also looks as though these other icons are configurable, removable and addable as well. This looks very promising indeed.

In my opinion; Ideal for visiting those "Dodgy" sites that you "stumble" accross, now and again.

if you like the idea of sandoxing check out Qubes OS ...

Very interesting indeed
Will be checked out

I still haven't checked Qubes
Anyone tried and tested it?

I downloaded it and tried to run it in VBox.

http://distrowatch.com/table.php?distribution=qubes

Wouldn’t boot

It says in their installation guide that installing it in any virtual box wont work Möbius :

Note: We don’t recommend installing Qubes in a virtual machine! It will likely not work. Please don’t send emails asking about it.

I'm looking into installing it on USB and trying it

Instructions? Really, are we suppose to really read them?
