Блокирует все гифки, даже статичные(

It's a bit weird that the addon needs to be enabled after installation. I mean, I installed it for its functionality. But worse than that the placeholder image have no max size which can lead to them being gigantic when they are replacing a simple animated emoticon. A very simple addon that needs some very simple fixes to be really useful.

Thanks for this. Was about to rate it 4 stars, but then I visited Gizmodo. Damn, too bad - that kind of flicker could trigger an epileptic seizure. Otherwise works fine when new page is loaded. and icon is on (blue). If not, turn on and reload existing page. Would be nice too if gif just stopped instead of removed, and of course with a single left click;)
