This is a tragic loss, I can't be grateful enough to the author, such a fantastic tool.

I even started installing it in my parent's computers (not advanced users), reducing to 0 the amount of time I had to intervene to fix their computers. The trick is to configure it in blacklist mode, instead of whitelist. This way it only blocks requests from domains in the blacklist and frame elements. Just with this change you get non-power users out of trouble in their surfing habits and impacts negligibly their use.

I have taught them that if a web is blocked or doesn't work properly is most likely not a web they want to use but that there is also the possibility to turn it off using the on/off button (that they should use very judiciously). In this mode it is not too different from setting up Hosts file but they can understand better what's going on and how to turn it off if needed.

Or you can use it in whitelist mode, but with all things like Cloudflare and ReCaptcha globally whitelisted. It's good that way too.

But yes, for your parents, black list mode would be good. It would be like uBlock Origin.

Any pointers on how to do this? I run into problems with online purchases, and find out easier to switch to chrome than try and authorise various sites on the fly.

If you want to replicate that kind of configuration that is as painless as possible you just have to go into the extension options/configuration. Head to the "My rules" tab and you will find a rule, towards the top of the rule list, that says:

"* * * block"

This rule acts as a default blacklist. If you switch it to:

"* * * allow" it will allow everything by default (except the blacklisted domains, which overrule this).

Then in the "Assets" tab you can configure your blacklists, I can recommend Steven Black's lists. He curates and consolidates several of the most famous ones:

He maintains several variants according to themes you may want to ban (adware, malware, fakenews...). Choose the combination that suits you.
