Browser clear history can be done by running Opera always in "private mode"
Use the shortcut on you desktop (or make one if you've throwed it away..).
Right mous on the icon and go to the "target" fill out field.
Change it to:
"C:\Program Files\Opera\launcher.exe" --private
or
"C:\Program Files (x86)\Opera\launcher.exe" --private
Depending upon the location where the opera.exe is.
Click ok and it is done...
The moment you close the browser all history is gone automatically...
The (important) consequence.... is that after you reopen Opera it does not open the preferred pages... I think (did not test that as I do not want to loose my current pages..)
It would be great if there was an X on right side of entries in suggestion list when auto-complete address bar,
to remove entries/URLs not wanted. #request
One thought is that, depending on how/where DNS lookup is being performed in all the generation and handshaking and relaying of the VPN traffic, there might be a glitch (or poisoning?) that is sending traffic routing to the Google .ua site rather than the desired one.
