Application error: a client-side exception has occurred

I was on 'https://jinxxy.com/market/browse ' and went to 'https://jinxxy.com/market/avatars' using the 'Discover' Tab on the left side. (Issue is also on the other Discover items: Everything, Avatars, Assets & Props etc. (not the prices or other things below)

After clicking I get a black screen with 'Application error: a client-side exception has occurred (see the browser console for more information), I am logged in on Jinxxy (username: Fluff) - I am using Firefox

The issue might be related to a extention that I am using and jinxxy page doesn't have a null handler?

like when a product/node is already removed it doesn't check if its still exist before trying to delete it because of a page change? (thats my guess)
