There's this annoying thing that some websites are doing that moves a video to the right side of the screen when you scroll down the page. This is the normal code for the site: <div class="video-container" style="height: 450px;">, but once you scroll, and move a hair past the boundaries for the video container the code changes to: <div class="video-container sticky-video sticky-right" style="height: 450px;">. I tried using yesscript and was not able to solve the issue. I also tried NoScript, with no luck, but I might be missing something with NoScript, like the option to block a single JS file from a domain. All I've seen is the ability to allow all scripts from domain X. I'm assuming this code change happens because of the OnScroll.js file the site access, but I can't say for certain. Things are layered way too well for me to track it all down. If I use the web developer tools and inspect the element, then delete just the right bit of code (which I can't seem to remember anymore) everything works like I'd like it to. Simply put, I want to know if there's a way I to configure Firefox so it will block / ignore dynamic HTML & CSS, preferably domain specific. Even better would be a way to block that specific code change. This is frustrating because most of the time I don't care about seeing the video, I simply want to listen while I browse the page, looking for other stories I might be interested in, only to have a video player blocking my view of other objects on the page.
