cannot block gif in general.

Vigtig udvidelse til Firefox. Det næste må være Tinnitus.

It is a very good add-on; but I have one issue with it - if the gif is a still image, it will display the text 'analysing gif' indefinitely. I can work around this by disabling the extension in private windows and browsing sites which majorly use still .gif images in said private window, but it would be nice to have an option to disable the add-on on specific sites. Other than that, a brilliant and useful add-on.

I have photosensitive epilepsy. It's so bad that thunderstorms put me at risk of a seizure. A lot of GIFs on Twitter are very flashy, and this makes being on Twitter safer for people like me. I cannot recommend this enough.
