Why is Firefox not blocking pop-ups? 

Sometimes, even after installing a pop-up blocker on your Firefox, you may find that it is not doing its job. So, why do I still get pop-ups when I have them blocked?

• Conflicting ad-blockers – If you have multiple ad-blocker extensions installed, they may be conflicting with each other and hence can’t prevent the pop-ups.

• Outdated browser – If you’re not getting the pop-up blocker, it could be that you’re using a version of Firefox that doesn’t support it. Check whether there is an available update for your browser and try again.
