how to block a meta refresh tag?

I was editing a website via its CRM. I put in a

<meta http-equiv="Refresh" content="0; url=https://www.website.com"> in the home body to check if it works.

Now I am unable to get rid of this tag. Whenever I try logging in as admin - it keep redirecting me. Any way to stop this? I am stuck. I do not have root access to the domain.

Solution

Open Firefox. Type in address bar: about:config search for accessibility.blockautorefresh Toggle all 3 to true.
