There are times that Mozilla can be slow. This is especially true when you have many windows open and a certain number of them have animated GIFs. At times like this, you can look at the CPU Mozilla is using to find it at 50 to 60%. To reduce CPU usage, you can either have animated GIFs animate once, or not at all.

To do this, open the Preferences window and then go to Privacy & Security -> Images, then in the bottom section, there is a place to configure how many times a GIF should loop. Choose either 'once' or 'none.' Looking at Mozilla's CPU usage afterwards, you should see it drop back down to something a little more acceptable.
