Site: https://community.algolia.com/marvel-search/ I am able to scroll using Chromium-based browsers. Unable to scroll using Firefox (65.0.2 (64-bit), Debian Stretch). Interestingly... Pale Moon (latest version) suffers from the same problem (I thought that after all this time, the rendering or JS? had diverged sufficiently). I also used a new, untainted, FF profile to test further (no extensions loaded). Still unable to scroll on this site. Attempted to reach the author of site but was unable to find any contact info anywhere. This is the first and only site I've had this issue with (algolia is not the problem, https://hn.algolia.com/ for example, works fine even with extensions loaded). Thank you for any help. I like the site in question and hope to use it with Firefox.
