The extension does not work under any circumstances. On Reddit, this extension only managed to block two GIF animations. This extension urgently needs an overhaul, as nothing has been done to this extension since 2020.

As others mentioned, it doesn't work. Using about:config -> image.animation_mode -> set value to "none" or "once" is much more effective.

It blocks .PNG photos. I could post a .PNG photo on my Facebook page, but not on a friend's page. It left a blank square. Took me a while to find out why. Also would not prevent a large GIF from playing that someone posted as a Facebook comment.

this is yet another glaring example of the most ill conceived, useless add-ons on AMO as well as another reason to not trust anything coming from add0ns (dot) com

rather than installing this garbage, those that don't wish to see animated GIFs should set 'image.animation_mode' to a value of 'once' in about:config

It won't block the files it promises, possibly because it won't toggle to enabled from the Firefox menu.

The setting of "image.animation_mode" in about:config controls image animation with the values of "none" (no animation), "once" (runs animation once), and "normal" (will run animation constantly).

Didn't work anywhere I tried it. And yes, I made sure the pos was enabled.

Doesn't do anything at all. And yes, it was enabled when I tested it.

Did not work at all on any site I tested (gifs still worked) and would rate it lower if I could.

install this plugin and go see Gizmodo's website for instance

it does not do anything

I've been using this for a couple of days on several websites that have a ridiculous number of GIFs on them and I haven't seen a single one actually get blocked. This just doesn't work at all.
