On both Fennec F-Droid 57.0.4, on LineageOS 14.1, and Firefox 58.0, on Ubuntu 16.10, websites such as https://www.bgemyth.net/forum/index.php timeout and end up displaying a blank page, when browsing using LibreJS 7.11. The problem goes away if I whitelist all JS from bgemyth.net. Seemingly the site uses some non-free JS to position some background images, but it is handled much more gracefully by LibreJS 6.0.13 (on IceCat 52.3.0 desktop, and IceCatMobile 52.4.1).
