Firefox 支持论坛

I think it's remiss there is not an obvious way to prevent any specified websites I choose, from ever loading on my system. Simple on my iPhone! Not on Windows 10, Mozilla Firefox.

 I find when I accidentally click things on my touchy touch screen or try to back out of a page I opened in a new tab (Nothing to go back to), sometimes the page is set up to repurpose that action, as a request for an advertisement or some other undesirable page, often the same few abusive jerks.
 I Should Be Able, With A Single Click to Block, ANY UNDESIRABLE PAGES! 
 Why isn't there a simple list, I can populate myself, on my system(?)  again, my iPhone has it!
 I'm old.  Reading about widgets and add-ons is like reading Greek, don't get it and don't want to have to learn!
 When did everything become self help?
 We need answers that say, click here to be directed to a page with an explanation and another button to click, maybe answer a few simple questions (NO Words Invented This Century, PLEASE!), and it is done!  PLEASE!
 So, Add A Blacklist Button To My Home Screen!  I feel like there is one, it is just some new term and unsearchable unless I know the new secret made up words!  Ridiculous Everything Is So Damn Hard 90% of my online time is trying to fix crap, find answers, etc. Sucks!
