The post in question is "Is there a way to rename menu items in Firefox?"
Generically speaking the OP is saying that "because a third party application has a particular bug/limitation, an Apple feature/function doesn't work." The OP then poses the question "how can the 3rd party application be modified so that Apple's feature/function meets my needs."
To me, this is an issue that falls within the realm of the developer of the 3rd party application. Especially so since the bug/limitation (specific to the question) is consistent across all platforms (macOS, Windows, BSD/Linux).
A moderator seems to disagree citing that "because it runs on macOS, the question is "on topic." A lot of things run on macOS, that in and of itself doesn't make it on topic or something that can be answered. For instance the question "How can I access the source code of my mouse via the terminal?" involves a product that technically "works" on macOS but there's no claims of support or compatibility; even the Linux support is from another independent party.
That said, rephrasing or reworking the question to state "because a a third party bug/limitation, Apple's feature/function X doesn't work. Is there a way to work around it so I can accomplish Y" would be easily keep it on topic.
