Thanks for the feedback! I'm glad to hear the blocker is working well.

I'm sorry to hear you experienced Firefox slowing down. That isn't the intended behavior, and I'd like to investigate it further. If you have a moment, could you let me know which version of the extension you're using, your Firefox version, your operating system, and whether the slowdown happens on startup, while browsing, or only on certain websites?

You can also email me at support@monolab.dev with those details. I'll do my best to reproduce the issue and improve performance in future updates. Thanks again for taking the time to leave a review!
