Hello! I just downloaded Firefox Developer edition, and the first page I see is https://www.mozilla.org/en-US/firefox/66.0a2/whatsnew/. As I was using the page, I noticed some broken links.
This “Start Now” button leads to https://devtools-html.github.io/, a site that gives a 404 page error.
Not sure if this is the right place to post about this, since this isn’t strictly about Firefox Developer tools, but is about the Firefox Developer Edition browser.
