Testing issues with mozilla firefox on Mongo DB/Mongoose challenges

Greetings.
Previously, I did a post asking why I was getting: “Duplicate key error collection…” in the console for all the query methods related challenges after I submitted my project link.

Turns out, the issue actually wasn’t due to my submitted project but because I was running the FCC page on Mozilla Firefox. Tried on Google Chrome afterwards and had no problems.

Regards;
