@gilesgoat 'java' or 'javascript'? 
because if it's 'java' then waw! it's been forever seen I've really seen (or at least noticed) something using java in the browser.
@loganer You are right is JavaScript, that is the message :
"To use the Mastodon web application, please enable JavaScript. Alternatively, try one of the native apps for Mastodon for your platform. "
@gilesgoat @loganer checking on this, will update you asap
@gilesgoat @loganer nothing changed on our end to cause this as best we can tell, but will keep an ear out for anyone else having a similar issue in case there's something deeper to dig out and deal with
@gilesgoat @loganer one comment I received was to ensure you're using the icon marked below, not the one to the left...
