Don't work WEBM

希望能更新，Fanbox不能正常使用了

It's great but you can't convert Ugoira to WebM anymore as they generate to 100% and then do nothing. It's been that way for a long time now, I'm talking 1 year or more.

you have no idea how useful this toolkit is
thank you very much

Eats up too much RAM, just by activating the add-on it adds up almost 1GB of RAM consumption by the browser (I only had about 7 pixiv tabs open). When you open many tabs at once it causes the browser to lag heavily and even crash. The crashes didn't happen before last Firefox update, not sure about the RAM consumption.
