A couple days ago I was trying to enable silverlight in firefox with pipelight. I followed the instructions here http://www.infoworld.com/article/2697813/install-silverlight-alternative-pipelight-in-ubuntu-14-04.html
It wasn't working for me so I disabled it and uninstalled. Since then firefox will sometime act up when visiting sites with flash. I don't know what pipelight did to screw up my firefox. Any idea on what I can do to fix this?
