Chrome won't let me log in. Firefox just redirects.

Suddenly Chrome won't load the page.  It used to let me bypass, but now it refuses. 

Firefox is worse - it just redirects to the Netgear page, where support is unavailable.  I know it's old.  But I can't afford a new cable modem every year.  This is JUST INSULTING that I have to go to the community for help. 

Solution 1: log in and change the setting to https://.  I did this before.  It didn't keep.  And now I can't log in, so not much help. https://kb.netgear.com/000064542/How-do-I-enable-HTTPS-when-accessing-my-NETGEAR-router#

Solution 2: get the app.  IT'S NOT A PHONE, IT'S A COMPUTER. How am I supposed to get a phone app to work on my computer???

Someone help?
