Opera 11.62 Release 2012-Mar-26 Changelog Opera 11.62 Version history

Proxy settings

In recent versions you can set a common proxy setting for all protocols, in older versions you must fill in separately. Enter server address 127.0.0.1 and port 4001 (you can change 4001 to some other number in JonDo settings, then use same value in the browser proxy settings too). For Tor the settings are similar, just the default port value is 8118. Make sure to cover HTTP, HTTPS and FTP protocols, for possible exotic or archaic protocols like Gopher you can enter invalid port 0.

Control JavaScript

You can disable JavaScript either completely, or selectively using the NotScripts addon.

Control plugins

Preferences -> Advanced -> Content -> Enable plug-ins.

Control Java

Java is needed to execute JonDo but Java also serves as a browser plugin than can bring a security and anonymity risk. Disable in Preferences -> Advanced -> Content -> Enable plug-ins. The other and probably safer way is to install JonDo as "portable" - in that case Opera (like any other browser) will simply not find the Java used by JonDo (there should be no other Java on the system).

Block URLs and advertising

Opera checks the file urlfilter.ini as a block list. The file can hold full names as well as RexExe, matched URLs will not be shown. A list can be downloaded from here: https://www.awxcnx.de/download/urlfilter.ini (right click). Place the file into following directory:

  • Windows (portable Opera) : inside the installation in "profile" directory, besides file "operaprefs.ini"
  • XP (if Opera not portable) : C:\Documents and Settings\...\Application Data\Opera\Opera\
  • Vista: (if Opera not portable) C:\Users\<username>\AppData\Roaming\Opera\Opera\
  • Linux: $HOME/.opera/
  • OSX: /Users/<username>/Library/Preferences/Opera Preferences/

You must restart Opera for the changes to take effect.

Other risks

Opera still has the Font-Face-Problem in version 11.62 :

Option:User Display Mode

User Font and Colors set to false

Another problem is the History-Sniffing , it can be fixed this way:

Option:Visited Link

Visited Links State set to 0
