It's too bad, but I have to remove this add-on because there is no way to manage notifications.

I like TickTick and still use it on my phone, but this extension somehow breaks the JS from running properly on certain sites so I had no choice but to uninstall it.

打开不了浏览器了?

Doesn't work as it should. All it does is open the web-based inbox of your TickTick account. It doesn't take the link of your current page and create a task pop-up for you to fill out.
