Lag in the freeCodeCamp exercises

I’ve been using freeCodeCamp to start my learning journey in coding. Recently, a problem came up where when I do an exercise for around 5-10 minutes, the website starts to lag. Before that, the website is fine, so I have to keep on refreshing the page so it doesn’t lag. If there is a solution for this, please tell me, as I want to keep on using freeCodeCamp.

What part of the curriculum?

What browser and operating system are you using?

What does the browser memory usage look like when the page starts to lag?

Did you try without extensions or in a different browser?

I ended up removing some of my extensions, and its working better now. If it starts lagging again I will let you know. Thanks!
