I just tried opening the Monkeytilt website, but it wouldn't load. I just see the logo that represents that website is loading (I guess), but I couldn't get past that. I even tried force refresh (Shift + F5), but it didn't help. Then I tried using Chrome (Edge is my default browser) and the website loaded almost instantly. I'm not sure what's the problem, but I can't seem to open the site in Edge.
I just tried it in my Edge browser, but no problems occurred, and it ran smoothly. There is a possibility that you need to clear the cache and cookies on the site, for a simple method you can try the following :1. Click on the Lock image, then click on cookies and site data
2. Choose monkeytilt site (or maybe you could choose all ), then remove it and click Done
I hope this could help you solving the problem, i often facing the same problem on other sites, but by clearing the cache and cookies usually help solving this matter.
