Firefox does not animate my gifs

Keywords:
firefox gif not animated

Problem:
Why is my animated gif working fine in IE but not firefox?

Solution:
The solution was on mozillaZine - I'm fairly sure I haven't turned image animation off explicitly, but to turn it on again:

1. Type about:config in the address bar


2. filter for "image.animation_mode"


3. if you're like me, you'll see this is set to "none". Change this to the default value of "normal".
