During my last Network Monitoring found out that MANY of „free“ Software calls home permanent
.. if you want to be safe, block all OUTGOING Traffic by a Firewall or local DNS Server and use a Proxy with Auth Mechanism!
If you want to be more secure, on Linux you can isolate used programs on different Users! All you need is installed by default!
Add a new User for eMail and Browser to the System with:
$sudo adduser mailuser
$sudo adduser webuser
now install if not installed by default „gksu“ User Switch
$sudo apt-get install gksu
copy now the default App Links to webuser’s Home Desktop, for mailuser enter mailuser’s name
$cp /usr/share/applications/firefox-esr.desktop /home/webuser/Desktop/firefox-esr.desktop
edit the firefox-esr.desktop by right click on nautilus or a editor and change command line:
gksu -u webuser -w "/usr/lib/firefox-esr/firefox-esr %u"
save and exit
Now to test click on the Firefox App Link and a Password is asked! Enter the webuser password and you use Firefox on a isolated Account!
Do same for thunderbird eMail Client! that no bad Code can access your Emails!
Set the Home Folder rights for webuser and mailuser to 700 with:
$sudo chmod 700 /home/webuser
$sudo chmod 700 /home/mailuser
Remark: Same Technics available at Windows or other Unix Systems, alternate use VNCSERVER! a App to run Desktops inside Desktops!
Advantage: Programs run on isolated RAM Space!

A free Howto to get a free Chromebook Replacement: Called Firefoxbook
Everybody knows a product called chromebook, but you must not buy such a laptop with branded OS! Here is a small Howto get a similar Laptop with free firefox.
How does it work? Easy, the Laptop boots from Stick or CF-Card to RAMDISK, the firefox profile and cache is always new created at non permanent RAMDISK. The private Mode surpress cookie and other waste. Only the Window Settings are stored (Fullscreen/ F11). After boot the Internet is connected and Firefox is shown on Desktop.
All you need:
a Laptop, can be a older one, i prefer Thinkpads
a Wireless/LAN Card if not available inside
4GB USB Stick or 4GB CF-Disk with ATA-CF-Adaptor
Time to work
Tinycorelinux at CD source
Download Tinycorelinux and burn it to CD
reboot the Laptop on the CD to tinycore
open a Terminal and enter #sudo tc-install
reboot the Laptop and remove the CD
boot the Laptop on the USB Stick
check network connection
if not available plugin LAN cable reboot again on stick
or setup WIFI with the WIFI Manager
check internet connection again
NOW LETS MAKE SAFE!
if the Laptop is online install firefox with: #tce-load -wi firefox
NOW!! Create first a firefox profile on the RAMDISK!!
do run as tc user #firefox -P
create new firefox profilename „tmp“ locate it at /tmp
now run as user tc #firefox, close firefox!
edit now /opt/.filetool.lst with #sudo vi /opt/.filetool.lst
add „tmp/localstore.rdf“ line, close and save
edit as user tc #vi /home/tc/.setbackground
add line „sh /tmp/tcloop/firefox/usr/local/firefox-official/firefox –private“
save settings to USB Stick called mydata.tgz with #filetool.sh -b“
run #sudo reboot
Enjoy a Firefoxbook with always safe browsing option! On every reboot the old cached data are really lost cause the profile is always placed inside ramdisk and never on chip!
Do always reboot or shutdown without backup by menu, or push only the Laptop Power Button to auto delete waste at poweroff. Other Browsers can be used also (Opera).
