This is a really helpful app. Until it stops working every few weeks. I have a block list of 200 sites and when it works, they do not show up.

I mostly use DuckDuckGo as my search engine in Firefox. I used to use StartPage mainly, these days just occasionally. I get the same problems whatever search engine I use.

Very often, the option to block the site is not appearing under the search results on my phone. But it still blocks those I have added in the past.

When uBlacklist stops working, when you open a second tab it will only block websites in the first tab. Pretty unhelpful...

Even worse, like now, it is not blocking anything and the option to block the site is not there. I have removed, restarted Firefox and re-added, no difference. Remove, reboot, readd, no difference.

It is a mystery how the basic functionality of the app can be so flakey. Whatever is going on with the coding, either in Firefox updates or uBlacklist updates, it breaks and functions are lost.

But when it works, I love it. Just wish it worked more often...
