You cannot even open the extension:

To protect your security, quillbot.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Hier hetzelfde probleem.
Ik installeerde Quillbot op aanraden van de 'Language Tool' die stopt met de gratis ondersteuning.

Als ik op Quillbot in de Firefox werkbalk klik krijg ik ook:
"Firefox kan deze pagina niet openen

Om uw veiligheid te beschermen, staat quillbot.com niet toe dat Firefox de pagina toont als een andere website deze heeft ingebed. Om deze pagina te bekijken moet u deze openen in een nieuw venster.

Meer info… "

Als ik naar de ondersteuningspagina van de extensie ga (ik heb een Quillbot-account en ben aangemeld) krijg ik alleen maar reclame en geen ondersteuning hoe dit op te lossen is.

Notitie: in andere browsers Google Chrome, Edge krijg ik deze foutmelding niet.

Dus: Quillbot, repareer deze bug AUB!

Funktioniert im Firefox nicht. Wieder mal absoluter Schrott!
Fehlermeldung:
Firefox darf diese eingebettete Seite nicht öffnen. Zu Ihrem Schutz erlaubt quillbot.com es Firefox nicht, diese Seite anzuzeigen, wenn sie in eine andere Seite eingebettet ist.

To my great dismay it doesn't work ;(
I installed this because the 'Language Tool' extension stops working after 14 days.
Like many others here I am getting this message:

Firefox Can’t Open This Page

Please Quillbot, fix this bug (pretty please)

Doesn't work - Embed failed

I like the site but the extension doesn't work.

Doesnt work Gives the error below:
Firefox Can’t Open This Page

To protect your security, quillbot.com will not allow Firefox to display the page if another site has embedded it. To see this page, you need to open it in a new window.

Does not work

I contacted QuillBot regarding the issue of not being able to log into the Firefox extension. I just received an email from them, and they clarified that there is no official Firefox extension from QuillBot available yet. They also mentioned that they will try to bring a Firefox plugin soon. Be cautious of potential scams.

i love this website or extension because it can paraphrase for you witch can change ai sounding text to human sounding text, if you don't like a word they paraphrased you can see all the word options, it has so many features like summarize, translate, citation, plagiarism checker and grammer checker, premium is also not that expensive
