Websites not working when enabled

[chraebsli]

I have the issue that when I visit some websites, some functionality of the website is not working. I had this issue on many websites, but that's the most recent one. Also, I'm not sure if the problem on the other websites is from this extension or because of others.

I tried to visit https://home.shelly.cloud/#/login, and it showed me a black screen. If I disable the extension, it works. Why is this error and how to fix it? I don't have a clue why this extension makes the error because it just shows JSON data nicely.
