I tried to click on the "browse topic" button but nothing happened. And there are no error messages in the browser's developer console. This made me thought there was no way to search for old topics, which was really annoying until the “browse topics” button happened to work, but only once. I'm using Chromium 45 on Ubuntu 2015.4.

Hello Kakurady
Same here, both with Firefox and Chromium. I've reported it.
Thanks for the report! This was fixed about 22 hours ago, but I forgot to post here.
