en The main problem is that sometimes it gets stuck in a loop and starts sending constant notifications, and you have to uninstall and install it again. Otherwise, it works perfectly.

en This extension occasionally sends tracking information about me to an obscure server. This means they're harvesting my data. There's no reason why a simple extension to block urls and make timer should be harvesting user data. 0/5. Removed immediately

en The very point of "pomodoro timer AND website blocker" is to have that tied together. Here we have two different capabilities, unrelated in one addon. All that saves is, possibly, some memory. I'd shift to 5-star the moment the app links it. Or at least gives an option to link it. Currently I've to manually block and unblock websites and it defeats the purpose.

en I mostly like this extension, but it keeps glitching. My computer floods with notifications from the extension. There are multiple timers going off at once. I don't know if this is a me problem or a problem with Nucleus. I just wish this extension would work without constantly glitching.
