I have a fix, it is basically this comment in this issue.
Issue: #59
comment: #59 (comment)
Proof this works for your case:

import requests


def main():
    base = 'codeforces.com/problemset'
    base = 'codeforces.com/contest/2065/standings/friends/true/page/1'
    http_url = f'http://{base}'
    https_url = f'https://{base}'
    for url in [http_url, https_url]:
        for imper in ['chrome', None]:
            response = cf_req.get(url,impersonate=imper)
            msg = "OK" if response.status_code == 200 else "FAIL"
            print(f"[CURL_CFFI] {{{msg}}} {response.status_code} url={url} impersonate={imper}  {len(response.text)}")

    for url in [http_url, https_url]:
        response = requests.get(url)
        msg = "OK" if response.status_code == 200 else "FAIL"
        print(f"[requests] {response.status_code} url={url}  {len(response.text)}")

main()

Thanks for the report and the screenshot.
You can see that Codeforces responding with a 404 on an API call. This is probably the user.ratedList endpoint which has been returning 404 for a few days now, I believe. This endpoint is necessary for the extension to make rating predictions, if it's down it will stop working.

So why did Codeforces turn it down? Who knows 🤷
Codeforces frequently takes the API down or blocks it with Cloudflare, without announcing it or communicating why.

There is a possible alternate way, which is #46. I haven't had much free time recently, but I will try to get that working soon.
