Forum website doesn't work on Firefox Win7

Tested with Firefox on safe mode / no addons. Win 7. FF 59.0.1 (64-bit). Have noticed this for the past month or so. User is presented with a blank/white screen on all forum pages.

Works fine in Chrome.

Console error output:

Same FF version, WIN10 - works flawless…

You’re right – I tested on Win 10 and it works fine. Very interesting. I’ll update the subject accordingly

I noticed this as well with FF on MacOS. I then tried the Discourse website and got the same blank page. Tried various cleaning steps, but did not manage to get it working.

Forum doesn’t work for me either on two different Win 10 machines. One is 1703 and the other 1709.
Firefox 59.0.1 on both machines.

Ok, found the problem. I recently disabled the web notification feature in about:config:

dom.webnotifications.enabled = false

If I set it back to true, the forum works fine. I hate web notifications!

Ok, I left it enabled in about:config but used the newer GUI method of turning off notifications. The forum still seems to work. Go figure. Hopefully this setup will basically disable push notifications still…

Nice detective work @drwtsn32 ! I also have the same notifications disabled.

Question remains: why is this setting render-blocking particularly for this forum / discourse?

Seems to be an issue with the discourse code.

Do ya’ll think the next step is to file a bug report on the discourse github? Happy to do so…

Posted bug report to the official discourse forum:
