Hi, use Ghostery and uBlock Origin together. You can take what ghostery blocks and use it to figure out uBlock. Note : they can break sites that need 3rd party cookies for Video to play.

If need or want added protection as well as block 3rd party cookies can use https://addons.mozilla.org/firefox/addon/malwarebytes/?src=search

Do you use the black themes ?

Thanks for the Ghostery suggestion, Ghostery hasn't punched me.

Malwarebytes has punched me, when I'm trying to get sites to stop punching me with pop-ups, so I'm removing it.

I don't know anything about themes, but I find black on grey easier than the reverse.

Ad blockers work by blocking requests to prevent the browser from loading content. A website can detect this and act upon this. Something that might work in such cases is to use userContent.css to hide specific content. When you use userContent.css then all involved content is still requested from the server, you only do not see it. You can use a property like visibility: collapse!important or visibility: hidden !important or set the opacity to a low value like 0 or 0.1. That way items are still in the DOM, but you do not see them. This requires some effort to set up and is thus only useful for web pages you visit regularly. This also assumes that you know how to use the builtin Inspector to locate items you need to block and find what selector you need to use. In most cases you need to move up in the DOM tree to find what parent element you need to block if you right-click specific content. The Page Inspector has a toolbar button that allow to move around on the page and see what gets selected in the DOM.
