Thank you so much for the feedback! Your idea about being able to disable the "Disable" button on the page that appears on blocked sites is a great and very logical idea, I will for sure implement that and include it in the next release!

In regards to the bug you've encountered, I would be very interested in fixing it so if you find the time to get in contact with me, i would greatly appreciate it! If so, you can email me at nodistractions@jakobs.work or, if you have a github account, open an issue at https://github.com/AsciiJakob/NoDistractions/issues

Some information you could provide is: whether it happens on all domains or just some specific website(s) and whether or not you get the "Failed adding current domain" error message. The feature seems to work just fine on my PC and my laptop, the only sites it doesn't work for are unusual ones like a "new tab" tab or the browser settings tabs as these can't really be blocked.

Edit: I figured out what you meant, it turns out i forgot to make it save the changes after adding the "current site". I have now published an update with a fix as well as with the feature you requested. Thank you!
