I know my Firefox (Win 10) blocks ads because I can see where they were supposed to be. Also, Youtube ads at the beginning of a video last only 1 or 2 seconds. But I've forgotten how I achieved that. I can find no evidence of an ad blocker on my computer or my Firefox browser. How can I find out how ads are blocked?

Firefox shows a purple shield instead of a gray shield at the left end of the location/address bar in case Enhanced Tracking Protection is blocking content.

  • click the shield icon for more detail and possibly disable the protection

You can check the Web Console for relevant-looking messages about blocked content.

That seemed to be all about trackers and harmful scripts, not about blocking ads.

You can find out whether you have a content blocker by looking at Add-ons and Themes (ctl+shft+a) > Extensions. Otherwise, do you have a hosts file?
