How can i disable ipv6 in Opera? Windows version.
Disabling ipv6 in Windows or using other browser are not acceptable options.
As opera does not have the feature a solution could be forcebindip
where 192.168.1.25 is the ip of the interface you want to use
This application redirect any connection to a specific interface and keep it there.
Just replace all your opera shortcut to point them to forcebindip
As this program is source closed you could be sceptical in a perspective of using it all the time, i personally disassembled it and checked every action and it seem that it's a clean application.
