Browser extension issue with basic access authentication

Hi I recently tried to use a new self hosted app (Suwayomi) and as soon as I add an auth to access the app, I get network errors, at first I tough it was the app or my NAS the issue but after a lot of troubleshooting (and using my phone to connect to it) I found the issue was both my browsers... It worked on private mode so it was one of my add-ons so I disabled them until I found it was the mooltipass one the issue. If I remember correctly there is a function in it that display a page to log on some websites instead of the "pop up" login window but I think it doesn't always work or at least not in this case. In brave if I withdraw the extention's access to the nas' hostname it works but it's impossible in Firefox... They say they use "basic access authentication" and it's in http so maybe it's linked? Can you do something about it? Thanks.
