Форум сообщества Firefox

i have tried LITERALLY EVERYTHING and i can just not connect to my site that uses http, it constantly redirects to https which DOES NOT WORK. and i am trying to connect to my server here so its kinda important but i clearly CANT access it.. i have watched countless forums, videos, addons. but nothing helps so please if anyone knows anything about this thatd be amazing.

ps also i have connected to the SAME ip/http server before using firefox, but now it does not work.

I don't want to "update my software" every day. How can I turn this function completely off ? This continuous badgering makes me want to switch to another provider.
