I started using it just for batches that lag and get throttled a few months ago, and found (to my surprise) it loads them faster than Chrome and Firefox. Now, I pretty much use it for all batches during high-traffic Mturk hours. I'd like to do everything in Chrome, but for whatever reason everything is so slow to load lately in Chrome, but only on Mturk....I don't have an issue with any other sites. I do not really care for Edge at all for any other purpose, but as long as it loads my HITs fast, I'm forced to use it.
I guess it makes sense now why the footer wasn't affecting any HITs in Edge, too....since I only use MTS with Chrome and Firefox. lol
