Pretty good but creating webms never works for me, goes up to 100% but then doesn't saves it.

I like it
it is easy to use

The most useful and convenient pixiv tool you can find in the internet.

when you try to download the gif it only reaches 1% and then says that there is a connection error and when retrying it does not work.

Doesn't work.

Incredibly easy to install and use with a simple and easy to use settings page. I'd love for a gif convert to webm feature, as many animated work on pixiv with this add-on can only be downloaded as gif or apng, so a gif > webm would be great. Otherwise, fantastic add-on.
