Was there a link to the project on Github? I think that you've mistakenly shared Github's search tool/path
Yup, it's pointing to https://github.com/search
I expect it's the https://github.com/search?q=repo%3Amozilla-firefox%2Ffirefox... link that phoronix used in lieu of linking to an actual github issue.
Here's the Bugzilla link which was closed last month: https://bugzilla.mozilla.org/show_bug.cgi?id=2021722
