ChangeUserAgentInOpera

It is possible to change the user agent Opera is sending to webservers even though there is not GUI option for that.

Edit the file ~opera/opera.ini and look for the following line:

"Spoof UserAgent ID=3"

Change this to 1 for real Opera UA string.

Have a look at the following website to have all the other options explained:
