Go to opera settings then uncheck "Block ads and surf the web up to three times faster" >>> everything will go as you wish

i just giving an example i don't intent to make advertise to any website .. if there is an option to edit my post i will edit it and hide website name .. I'm only sharing an idea that may help somebody someday .. thanks
skoy21 .. thanks for your tip ,, but my idea is about opening a website via command line .. thanks

great note .. it is now ("C:\Program Files (x86)\Opera\launcher.exe" --ran-launcher --remote www.duolingo.com)
thanks

this is a simple example of how to open a url through command line .. it is useful if you want to make a shortcut for a site in your desktop or you want to pin it in your taskbar

"C:\Program Files (x86)\Opera\31.0.1889.99\opera.exe" --ran-launcher --remote www.duolingo.com

this command will open duolingo website .. don't forget to choose an icon for the shortcut to look nice

thanks .. it is worked
but is there is away to do this by one click

hi everybody , i'm asking about an extension or any trick helps me to open a set of urls (more than one url - every url in new tab) in one click
thanks

thanks opera i have managed the problem by doing this
1- install this extension to enable chrome extension in opera
https://addons.opera.com/en/extensions/details/download-chrome-extension-9/?display=en
2- then adding this extension to opera
https://chrome.google.com/webstore/detail/click-to-tab/ebicmkkcnhdiglneianohfjapmanjoek?hl=en

.. finally i now can open every link in new tab by default

is there any security problem if i returned to opera 12.7 .. last version of old opera?
and what other problems may i face using opera 12.7
thanks

it is sad to hear that specially because this function was available in the past
why opera don't support this feature .. i don't know if it is available in chrome or not but what i know is opera was always customizable .. what is happened?!

twitter for example
in twitter i receive tweets from different os like android and ios and windows
i'm running windows 8.1
