Works great almost always but I've recently run into a weird issue (i get around it by just disabling the extension on this website)

I am forced to disable this extension while using Discord.

With the blocker up, every time I try to switch to a different channel in a specific server, Discord does its normal thing and opens the channel, but then also the blocker tells me it has blocked a popup and asks if I will allow it - when I allow it, it opens the channel in a different window. So now it will have the channel open twice in two windows.

When the blocker is off, discord just swaps to the new channel without any issues and doesn't have any popups.
