Breaks XML document tree rendering.

Keeps crashing and it's a chore to get it working again...sadly it the only choice.

It's breaking Youtube thumbnails.

I HOPED THAT IT IS support more sites

Works well. Some issues I noticed is that it does not play gif files on Pixiv and you are only given the option to view the file frame by frame. I haven't noticed any issues on other websites when it comes to playing animated videos/gifs. If you are looking at Facebook Photos, your browser will start to lag super badly the more you scroll down. This is fixed by disabling the add-on. Decent add-on.

The zoom mouse scrolling is finally fixed after years!

It's good, but...freezes the browsing on facebook when i chose to click on fb tabs. Even the Firefox shows a pop-up that the specific extension slows down the browsing. I hope you to fix that soon.

Useful in Plurk

good ext love it
