Facebook messenger not working #399

With user.js installed (both hardened and relaxed versions), Facebook messenger does not work. I get an error:

ErrorUtils caught an error: "c is undefined". Subsequent errors won't be logged; see https://fburl.com/debugjs.

That's weird. I use FB with the relaxed version and haven't experienced any issues. Are you using some add-ons that might cause problems?

How does it not work exactly?

When I click on the name of a person nothing happens. The first time it seems that the message window is displayed for a fraction of a second and then disappears.

When I click on messenger, the page remains blank, as shown
here

I did disable all plugins, and the behavior is the same. Firefox version is 60.0.2 (64 bit)

Try going to about:serviceworkers and deleting all serviceworkers. It corrected something similar on another site for me.

I get a message:

Service Workers are not enabled.

Well, maybe try enabling them, then? Maybe messenger doesn't work without them.

user_pref("dom.serviceWorkers.enabled", true); ought to do it.

I enabled them, but still the same behavior. Now in "about:serviceworkers" I get:

fb sw

Can you report the same with a fresh profile? Go to about:profiles, make a fresh profile and add the user.js (both strict and relaxed) and see if the behaviour persists?

Yes, it's the same with a fresh profile with both versions

So I was able to reproduce this (with non-ESR Firefox). Didn't find any quick fixes for this and need to investigate more.

It's svg.disabled.

Disabling SVG breaks way too many sites nowadays.
