Okay thank you.

This is what a header displays. Any information from someone that may help.

We cannot detect a running copy of GNOME on this system, so some parts of the interface may be disabled. See our troubleshooting entry for more information.

I am currently running Manjaro Gnome 3.18.2. I am having issues with adding Gnome extension from https://extensions.gnome.org web page through the Gnome Tweek Tool on the system. I went to there troubleshooting page as they suggest; but cannot find what I'm looking for. They advises to enable click-to-play extension and add Gnome Shell. I don't see that on Opera. Better yet, I'm confused and don't know about this. I am running the current version of Opera. Any suggestions?

Thanks got it. =-)

If you are running version 31, I had to install Pepperflash. You should be able to install it through synaptic package manager. I think it is listed as chromium pepperflash. However. If you do npt have the latest release of Opera 33 I would update to it. I have no problems with Youtube. I hope this is what your looking for.

It is showing a white window with black border

For some reason when I open the uBlock window addon is showing when I try to open the window. I'm running PCLinuxOS KDE 64bit. Can you help?

I installed it through Synaptic Package Manager. Good luck. =-)

I have found that to view all video that are not working with flashplayer you may also need to install the Chromium pepperflashplayer nonfree plugin. I'm using Linux Mint KDE 17.1. Just a suggestion. It works fort me.

I solved it by making sure the "adjust for slower websites" is not ticked in browser settings. I then rebooted and it seems to be working fine. I'm running Mint 17.1 KDE.
