When you opened the web browser did it install the plugins. First you have to install pipelight and then pipelight has to install the plugin. If it didn’t you may have to enable silverlight in the konsole. It does usually take a while to install but it should install the first time the browser needs it.
Try the following at the cmd line.
sudo pipelight-plugin --list-enabled
It should list silverlight. If it doesn’t try this:
sudo pipelight-plugin --enable silverlight
If the first one says something about pipelight not being found there is the problem. Another issue you may have is not having a User agent switcher which is required for some websites that check that ****.
