Ad Blockers

Firefox does not come with an ad blocker built in, but it does have Tracking Protection, which blocks some ad-related servers that have the potential to share your data across sites. If you are visiting a site that doesn't work and you trust it enough to relax tracking protection, you can do that by clicking the little shield icon at the left end of the address bar, then clicking the blue slider switch to disable protection.
