Remove the 'no-cors' option, which no longer seems necessary, but at the (#189)

same time creates problem on certain websites.

Difficult to confirm now, but most likely it was necessary in the past,
because otherwise browsers included an Origin header with the extension ID.
Especially on Firefox, this was problematic, since the extension ID
is a unique identifier.

But now with Firefox 148 and Chromium 145, I could no longer reproduce
that this workaround is still useful.
