Forums not working in Firefox
Why does this forum system only work in Chromium and not Firefox?
When I click “New Topic” in Firefox, it just shows a bar at the bottom of the page and a red circle with a white plus symbol.
Works here with Firefox 40 in Linux, Windows, and on Android (phone and tablet). I use it myself.
Maybe you have hit an early version just as the forums have been set up? Please clear the cache and try again.
Just tried it too, and it works flawlessly here… What OS are you using?
