Make sure to use always the latest version of Opera !
In recent versions you can set a common proxy setting for all protocols, in older versions you had to 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.
Adjust Header Data and User Agent
User Prefs -> Custom User-Agent
There you can enter a modified User Agent:
Opera/9.80 (X11; U; Linux i686; en-US; rv:188.8.131.52) Presto/2.2.15 Version/10.10

Alternative search engines in Opera
Launch for example Blekko.
Move the mouse arrow into the search field, with a right click call the context menu, and pick "Create Search".
You will see the menu to register a search engine (see screenshot). You have to set up a keyword, in this case "bl" (blue arrow). You have to decide, whether this one has to become the default search engine (red arrow).
Further privacy-friendly search engines:
All those are accessible with HTTPS too.
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)
You must restart Opera for the changes to take effect.
