Add the plug-in No Script

This will prevent server-side scripts from running in your browser without your permission. This plug-in blocks all java scripts from running on web pages. This is both a privacy and security plug-in. By preventing the applications from running the instant you visit a page, there is little risk of malware affecting you in the background if you go to a compromised site.

Modern web sites have hidden links to a multitude of other web sites. Many of these scripts that load have nothing to do with the function of the site you are visiting. They are scripts that connect you to other sites like FaceBook, Google, Double Click, Twitter, etc. This allows these outside sites to track your activity across the Internet even though you never went to their site. By only allowing the essential java scripts that make the desired web site function, while preventing the others, you increase your privacy significantly.

After installing this plug-in most sites will not operate properly. You have to train the browser for each site you visit as to what to allow and not allow. No Script will give you a nice drop down menu telling you what sites are attempting to run scripts and then you can pick the ones that apply to the site you are on while rejecting the trackers.

By default No Script allows well known sites to operate freely. We suggest you change the default setting to restrict everything and then set all permissions manually. For example, If you go to a website that uses Google Analytics to track their visitors then Google will try to load and run the java script to track you. If you have this disabled in No Script then you are less trackable without any functionality loss. All the search engines, tracking sites and social networking sites operate the same way. All of them are out to get every last bit of information on you in order to make money.

Download and install BleachBit.

Set preferences for regular mode (non admin) to “Start BleachBit with computer” and “Overwrite files to hide contents.
In the main menu: (depending on your operating system these options may vary slightly)
Check all the boxes under Chrome (If you insist on using it).
Check the temporary files and thumbs.db under Deep Scan
Check all the Boxes under Firefox.
Check all boxes under Flash.
Check Temporary Files and Trash under System.
Check all boxes under Thumbnails Cache.
Depending on what other software you have installed on your computer other options may also appear such as office suite files, video or music players.  Be sure to wipe these clean as well.
The admin version of BleachBit allows for clearing of various logs and restricted settings. This should also be set up and run often as well as wiping the drive free space.

Accept the warning about harming your system and be careful what changes you make.

Firefox has a feature called Prefetching that downloads pages (in the background) that it thinks you are going to click on in the future. This is a serious security flaw since in order to make this guess it’s saving lots of information of your previously visited sites.

The above setting should be considered the minimum required to a secure and private browser. We recommend the following plugins as additional defense methods.  These can be installed via the FireFox plug-ins menu or from the links.

HTTPS Everywhere, Privacy Badger, UAControl , User-Agent JS Fixer, Disconnect
