How to Block Pop-Ups on Firefox by Adjusting Your Browser Settings

Mozilla Firefox has its own inbuilt Tracking Protection. Tracking is the collection of data regarding a particular user’s activity across multiple websites or applications that aren’t owned by the data collector, and the retention, use, or sharing of that data. This means Firefox’s Tracking Protection blocks page elements that read and collect your activity and then save that information to a database. As a side effect, it can stop pop-ups on Firefox.

Opera browser also has a built-in ad-blocking tool. You can enable it in the settings of your browser and learn how to block ads on Opera using it.

How to enable Firefox Tracking Protection

    • Click the hamburger menu button (“≡” in the top right), Open menu, and choose Options;

    • In a new window click Privacy And Security;

    • Scroll down until you find the Tracking Protection option. Click Always to enable Tracking Protection on every website;

You can set a whitelist of websites on which you allow tracking. Tracking Protection significantly reduces websites’ profit from advertising so if you’re loyal to a particular website, you can add it to the list of exceptions (see step 4).

    • Go to a website on which you want to allow tracking. Click a tiny shield next to the website’s URL. In a drop-down window click Disable protection for this site;

disable protection firefox adlock
You’ll see that a shield is now struck through with a red line, and the website’s URL will appear in the Exceptions.

    • Do Not Track – you can send a signal to websites telling you don’t want to be tracked.

Nevertheless, this option does not oblige websites to stop tracking. Honoring this setting is solely voluntary.

So from now, I won’t see ads on Firefox Browser?

Though Firefox Tracking Protection works better than Google Chrome’s inbuilt ad blocker, it still doesn’t block all ads. For example, it blocks autoplaying videos on online players but leaves pop-up windows. On some websites, Protection ruins the way they are displayed. For example, if Tracking Protection is enabled on Buzzfeed, it leaves blank space where banners were supposed to be and also hides a comments section.

Well, a Tracking Protection is supposed to stop tracking not to stop adverts on Firefox. If you want an ad blocker, use something designed for that purpose, like AdLock.

Block Ads on Firefox with FlashBlock

Flash Block is a useful extension designed for Firefox. It takes control over Adobe Flash contents including adverts, games, and other Flash elements embedded in webpages. As you browse websites, it stops the loading of Flash elements and shows “Flash Content” placeholders instead. By clicking the placeholders, you activate the loading of the original content. FlashBlock is good because:

  • Allows to block flash content in all webpages at once;
  • Easy to use — 2-clicks to switch On/Off, 3-click whitelisting.

Remove Ads From Firefox With NoScript

There’s yet another extension helping to block ads on Firefox NoScript. It allows JavaScriptJavaFlashand other plugins to be executed only by trusted websites (for instance your online bank), while the same elements on the rest of web pages will be disabled. Whitelisting and blacklisting in NoScript extension is performed through a couple of clicks. 

Does Firefox Private Browsing Make Users Safe?

We’ve heard numerous myths that Private Browsing mode in Firefox helps to avoid ads, malware attacks, malicious redirects, etc. Let’s get down to business and make things clear.

Indeed, Private Browsing is a useful Firefox feature, because:

  • It hides your online activity from other people using Firefox on your PC;
  • Lets you browse in a private window that doesn’t save cookies and browsing history;
  • Hides your download history.

But it doesn’t make you safe as it’s believed. According to the official information posted by Firefox developers:

  • It doesn’t make you invisible, doesn’t obscure your identity;
  • Private Browsing doesn’t protect you from malicious attacks and redirects;
  • And it doesn’t protect you from adverts as well as from adware.

This means you can fall a victim to scammers, cybercrooks, browser hijackers, etc. We suggest you download a reliable adblocker instead of dozens of extensions and be safe and secure in your own ad-free internet.
