@tun123 English here please

Yeach, solved. I think it was facebook error.

That worked. Thank you very much! I must have disabled it at some point for some reason.

@alfredo-b-face There's a fix. If you can save the webpage as pdf, you can still copy. Though, it would break some lines of HTML code for a bulky website but will work for Facebook.
Otherwise, if you have desktop, the best option will be to download a copyright protection remover extension.
Good Luck!

@faveroo Please write the topic title in English and use only English here.

Topic closed as solved.

@leocg Of course I tried all of the mentioned. I think I will have to begin again by clearing out all my Opera data, and start from square one. I was just hoping this had happened to someone else who had a idea why it was happening. Or if anyone could help so I don't lose all the tweeks and settings I have already built into my present browser.

Like all Chromium-based browsers, Opera does not support Java - but I'm sure you really meant javascript (common mistake).
