Still interesting that they internally dont use bugzilla. I wasnt aware.

Some project managers use Jira. Developers use Bugzilla.

My heart goes out to those wretched souls.

I suspect the vast majority of bugs are exclusively using Bugzilla. Maybe they use Jira for roadmapping or security bugs.

Other open source projects plan in public. Bugzilla can restrict viewing security bugs.

Few other open source projects are as large as Firefox.

So?

The issues with Jira links don't have obvious connections to internal systems. I think the FIDEFE project is UI related.
