Console problem in website for submitting solutions

Hello everyone, I am experiencing problem with the website we are supposed to submit our solutions to the projects.
When i write some code out and try to run it it doesn’t show on the console. All i get is this image:`

now this has not been a problem for me whist working on my projects because I have used pycharm to work on my projects until the final draft was ready to freecodecamp’s website.

But in general it would be nice to know where the problem is coming from and if any other people have experienced it.
I don’t know if it is relevant to the problem, but I am currently using firefox as my main browser and have Ubuntu 20.04 LTS as my OS

do you mean on

I would try to switch off any browser extension you have

Yes, I meant exactly that!
And I don’t have any extensions installed (i just checked), though I did remember customising the browser using the about: config" page when I first opened firefox. I wrote a list of all the things I disabled/enabled in the aboutconfig page and the reason for doing this just in case someday i needed to refer back to it. here it is:
This was done some time ago, so some features might have become irrelevant in the new firefox updates

about:config settings start

Disable WebRTC:
WebRTC can give up your real IP even when using VPN or Tor. Type in

media.peerconnection.enabled = false

Enable fingerprint resistance: With this alone we pretty much negate the need for canvas defender, or any other fingerprint blocking addon.

privacy.resistfingerprinting = true

3DES Cypher:
3DES has known security flaws

security.ssl3.rsa_des_ede3_sha = false

Require Safe Negotiation: Optimize SSL

security.ssl.require_safe_negotiation = true

Disable TLS 1.0, 1.1

security.tls.version.min = 3
enables TLS 1.3
tls.version.max = 4

Disable 0 round trip time to better secure your forward secrecy
security.tls.enable_0rtt_data = false

Disable Automatic Formfill
browser.formfil.enable = false

Disable disk caching
browser.cache.disk.enable = false
browser.cache.disk_cache_ssl = false
browser.cache.memory.enable = false
browser.cache.offline.enable = false
browser.cache.insecure.enable = false

Disable geolocation services
geo.enabled = false

Disable plugin scanning.
Can improve functionality, as some sites scan for adblockers and script blockers. Should be used even on non-hardened firefox.

plugin.scan.plid.all = false

Disable ALL telemetery

browser.newtabpage.activity-stream.feeds.telemetry browser.newtabpage.activity-stream.telemetry = false
browser.pingcentre.telemetry = false
devtools.onboarding.telemetry-logged = false
media.wmf.deblacklisting-for-telemetry-in-gpu-process = false
toolkit.telemetry.archive.enabled = false
toolkit.telemetry.bhrping.enabled = false
toolkit.telemetry.firstshutdownping.enabled = false
toolkit.telemetry.hybridcontent.enabled = false
toolkit.telemetry.newprofileping.enabled = false
toolkit.telemetry.unified = false
toolkit.telemetry.updateping.enabled = false
toolkit.telemetry.shutdownpingsender.enabled = false

Disable WebGL
Allows direct access to GPU.
webgl.disabled = true

Enable first-party isolation
Prevents browsers from making requests outside of the primary domain of the website. Prevents supercookies. may cause websites that rely on 3rd party scripts and libraries to break, however those are generally only used for tracking so fuck em anyway.

privacy.firstparty.isolate = true

Disable TLS false start
security.ssl.enable_false_start = false
about:config settings end

you may need to ask to support, maybe they can tell you what’s interfering
