I did, I even tried in a new private browsing window and it still did it.
ETA: I manually deleted the www and it works fine (I had to relogin) and is not auto populating the www again. But if I open a new tab/window and type in sopuli.xyz it adds in the www.
That is weird. Definitely doesn’t on my system. Even Firefox.
Clear cache and remove sopuli from history to make sure FF isn’t trying to helpful by “correcting” the address?
