If you have included the profile directly in your Firefox (i.e. if you are not using the portable version), please use the "Delete JonDoFox" link in your Windows start menu. If this link is not there you will find it if you are clicking on All Programs -> JonDoFox. If you are using Linux just use the profile manager by typing
firefox -ProfileManager
on your console.
In the file FirefoxPortable\FirefoxPortable.ini, set the entry DisableSplashScreen to true
Yes. However, data about your visited websites wil then be stored on your local drive. This setting is therefore not recommended. For all people, who would like to do this nevertheless: Enter about:config in the browser line, get the entry browser.startup.page and set it to the value 3. Then go to browser.sessionstore.enabled and set it true. Moreover, set browser.sessionstore.resume_session_once to false and set privacy.item.history to false.
In JonDoFox, you may choose File->Launch another profile->[Profile name] to switch to another profile, e.g. to the Firefox "default" profile. You may thereby also launch more than one profile at the same time.
Alternative:
Close Firefox first. Then you may start the profile mananger by using
Windows
There, type:
firefox -P
Hints for unexperienced computer users:
Linux / Mac OS X
Enter in a shell or on a command line:
firefox -ProfileManager
All operating systems
If you would like to get the list of available profiles presented at each start of Firefox, just uncheck "Don't ask at startup" in the profile manager.
These problems may occur on very large USB flash drives (confirmed for Corsair Flash Voyager 2, 16GB). Please defragment the USB flash drive and repeat the installation.
If you just want to view web videos on common video portals, you do not need Flash in your browser. You should enable Flash in your browser only if you know what you are doing. Then, however, set at least restrictive security settings before:
In order to activate the settings manager, you first have to allow the domains macromedia.com and adobe.com for JavaScript. After that, you should restrict the storage space for web sites to "0" and additionally forbid storage of web site information (third parties) completely. This prevents you from getting so-called Flash cookies.
In order to prevent your IP address from being uncovered easily, you have to forbid your computer any Internet connections to the ports 80 and 443. You may do this, for example, by using a personal firewall. If possible, allow exceptions for the JonDonym network addresses. The JonDonym services are, in case of need, automatically reachable by other ports, but this may lead to delays when connecting. Moreover, the payment instance may only be contacted if JonDo has previously established an anonymous connection which serves as a tunnel.
In order to prevent automaticed attacks by Flash on your system, you should execute Flash contents only in virtual environments like VMWare or Virtual PC, or in a sandbox.
Hint: A lot of websites show Flash applications only if you have previously allowed JavaScript for these sites.
The file can be unpacked with a ZIP program. Such a program is integrated in almost all operating systems. In the ZIP file, you will find an installation help and an install script. You cannot start the install script directly from the archive. Start it after unpacking the archive files to a separate directory in a shell or on a command line typing:
./install_linux.sh
Hint: Firefox should be installed on your computer before.
In order to keep yourself from having to activate the dangerous Flash in your browser, you should always download web videos to your hard drive and play them from there. This also saves you the additional data traffic which would be needed to view a streaming video again. JonDoFox contains a download tool for doing this.
JonDoFox is, in its basic settings, not compatible with RefControl. But that is no problem because it surpasses RefControls referrer handling. However, if you do like follows, you may install and use RefControl without any restrictions:
extensions.jondofox.set_referrer to false
First, start your old Firefox profile using the profile manager. Then, save the bookmarks stored there into a file:
1. menu "Bookmarks"
2. "Organize Bookmarks..."
3. "Import and Backup"
4. "Export HTML..."
After that, close Firefox and start JonDoFox, also using the profile manager. Then load the saved file using the same steps as above, this time by choosing "Import HTML...", however.
The recommended method for an update of the JonDoFox profile is to "over-install" the version of JonDoFox installed on your system with the current version. Moreover, when updating single extensions (e.g. JonDoFox) using auto-update, you should normally face no problems as well.
Also the browser itself may be updated automatically. In case of major version hops, however, it may happen that one or more important extensions do not work any more.
The browser history is already deactivated in JonDoFox by default. That what you see in the address bar are just your bookmarks, for giving you faster access to them. From a security point of view there is no reason to switch off this behavior. However, if you are concerned (which is unsubstantiated after the current state-of-the-art knowledge of technology) that your bookmarks could be read by web sites, you should delete all your bookmarks and keep from creating new ones instead of fading them out of your address bar.
Just see the profile manager for further instructions.
Firefox has an automatic recognition feature for web sites that are known as fraudulent or as a malware distributor. Every 30 to 60 minutes, this causes an update of a local database from Google which holds the addresses of those web sites. The database is needed, so that not on every requested page Google has to be contacted. This procedure is thereby very privacy-friendly. If you moreover use JonDo, the database request is independently and additionally anonymized, of course.
If you nevertheless would like to abandon this recommendable protection, however, you may prevent downloading the database. To do that, change the following configuration settings in about:config:
browser.safebrowsing.dataProvider = -1
browser.safebrowsing.enabled = false
browser.safebrowsing.malware.enabled = false
This error occurs if you have encrypted your user directory with FileVault. Instead the installation program for Mac OS X, use the Linux installation program for JonDoFox. Unpack the file that you have downloaded. Now open a terminal, change into the unpacked directory and enter:
./install_linux.sh
You are probably using some other tools besides our JonDoFox, like Steganos' InternetSpurenVernichter. This program deletes, for instance, the JonDoFox preference which is responsible for setting the proper version number in your window title. That's why 'null' shows up. But not only that: Further preferences of your profile are changed due to the deployment of this tool without your knowledge let alone agreement. E.g., your search engine is set to 'Yahoo' and options of other extensions (Adblock, Profileswitcher) are changed. To cut a long story short: it is dangerous to rely on such tools in addition to JonDoFox. And to make it clear: JonDoFox deletes all the surfing traces and data itself during shutdown.
