@Vlad After updating Orion to the new release, both issues remain.
Snapdrop.net still crashes before loading, except now it no longer shows an error message, but just keeps trying to reload the site nonstop. Sharedrop.io loads but the device still doesn't show up on other local devices (same behavior seen on Safari, so I'm guessing this affects all webkit browsers).
Tested in both normal and compatibility modes, with a fresh install of Orion w/ no extensions.
Orion, OS version:
Version 0.99.122-beta (WebKit 615.1.11.7)
MacBook Pro (macOS Mojave 10.14.6 build 18G103)
