Disclaimer: I develop Waterfox. I think it’s worth noting that Librewolf provides unsigned binaries and at least on Windows, you need to trust a third party service to provide automatic updates.
Some constructive criticism, if you're open to it: The web page is just a bunch of standard marketing fluff with about 5 download links scattered around. It looks a lot like every other "product" website out there screaming, "trust us, it'll be worth it!"
If you really want to attract people like me to it, you can't just _say_ you're awesome, you need to _show_ us you're awesome. In your blog (which is hard to find), you express great gratitude towards your users and community. Where is this community, exactly? I might like to join it but I can't find it anywhere. I had to scroll all the way to the bottom of the page to find a link to the source code (which just says "GitHub," mind).
I had to search pretty hard to find out that it is open source and apparently actively maintained, so I will check it out after all. But I was seconds away from just closing the tab out of disinterest and not looking back.
