No way to navigate to downloads from unsupported system.
I'm trying to download the install file, but I'm on a chromebook, so all the would-be links just say "Your system doesn't meet the requirements to run Thunderbird."
When this happens I would usually expect to see a link to somewhere like "https://www.thunderbird.net/en-US/thunderbird/all/", but I don't see any link like this.
I was able to find that URL hunting through the archived questions, so I was able to download it, but (IMHO) there should be a way from that page/menu/whatever to get to *all* the downloads without your browser/client having to be verified, especially for folks trying to get links and urls for things like packaging and remote installations.
