This is the worst possible thing they could have done. I use this browser specifically for this feature and they've completely crippled it with every single one of the changes they've made.
The cap on resizing the video is what pisses me off the most as I have multiple monitors.
In what world would anyone think any of these changes was a good Idea is beyond me. I'll be moving on to another browser if it doesn't go back to how it was.
