I started Firefox 70.0.1 on Windows 10, entered .4-1 so it showed x^4-1 in the polynomial box, then I pressed the Factor button. The output with Pretty Print disabled is:

Code:
x^4 − 1

Irreducible polynomial factors:

    x − 1
    x + 1
    x^2 + 1

Roots:

    x1 = 1
    x2 = -1
    x3 = - 1 *i
    x4 = 1 *i

Time elapsed: 0d 0h 0m 0.0s
I do not have that NoScript plugin.
