it works, but only on/off globally and permanently, and without marking disabled GIFs

Doesn't work

Thank you. This does pause GIFs - both globally (then refresh the page after a change), or per picture (from the context menu from right click or Ctrl+Click).

Arturo (the developer): Please consider adding Resume/Continue menu entry to the context menu.

Has all the controls expected on a video player. Pause, rewind, speed etc.

doesn't work - pause button does nothing. EPIC FAIL.

Giving a 3 star because it doesn't actually pause the .gifs. It seems that it stops them from playing all together. I'm looking for a tool that will pause and then play gifs, to slow down the playback of a .gif. Unfortunately, this doesn't do that. But, otherwise a good and simple way to stop .gifs from playing in the browser.

It works just fine, you only need to reload the page in order to take effect

Only lets you enable or disable all GIFs on a webpage. Also, needs to refresh page to take effect.
