Steps to reproduce:

1. open the web developer tools
2. access this site for example: https://www.dianyingim.com/
3. you will find harder to render or check the html element.

Actual results:

You will find this site is using random rendering js with debugger keyword to block rendering html elements to block you to see the html elements.

Expected results:

I didn't find anywhere that I can block Debugger tabs or disable debugger keywords functions that I can use.

I try multi ways like using about:config to block all the debugger views or similar things.

Cloud we add some features that block website doing such things.

Unfortunately when I try to load the page I am blocked by the Cloudflare protection interstitial so I can't even reach the site to try to check what you're saying. Since I'm merely referencing the URL it's not any kind of "attack" as that page asserts so I assume that site has blocked the entire California Bay Area, or maybe everywhere except whatever region you're accessing it from. Hard to think of a legitimate reason for blocking someone who simply tried to load the site.

You should be able to stop this by disabling all breakpoints in the debugger. Yes, this is less than idea if you're trying to investigate the scripts on a malicious site, but it should at least let you inspect the HTML.
