Hi.
I've seen an old topic about this. An author asked about it 4 years ago. There is an answer that feature will be added in the future. I can't find any option for such action right now. Can I delete a device from synchronisation list or not?
Thanks!

Why Opera beta and stable was freezed at major version of 45 for i386?
Users with old hardware are deprecated now?

Hi again @bombacha,
The tutorial you linked to is no longer valid, it refers to a very old version of Opera. Sorry for the confusion.

browser-plugin-freshplayer-pepperflash

You don't need this package for Opera (and it will not be used); this is a wrapper that can be used to make Firefox use the PPAPI plug-in, it is not the plug-in itself.
The package on Adobe's site is called 'FP 26.0 for Ubuntu (apt)', you should be able to get this one from https://get.adobe.com/flashplayer/otherversions/ . Can you try downloading that one and installing it? It should install to a directory that will automatically get recognized by Opera.

Thanks, it helped!
