it works but somethings off, every now and then new tabs fail to connect as if you'd lost internet. but the loaded tabs you can navigate and request new pages. I have to disable to fix and then re-enable the extension. which defeats my particular use case. wanted youtube to load videos at a preferred resolution everytime. But I'm probably fiddling with this extension more than the effort needed to just correct youtube every video. it has loads of features that I'd like to play with but this bug happens so often I'd rather leave it off
