I get slowed response with script error messages and lockup after many attempts I t give me Firefox has crashed and needs to shutdown. Any other browser that I use everything is normal. The two websites it happens on are Breitbart.com and Breitbart/big government. I have used Firefox for years and love it and added features. Thank you, Eldon
