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

Tracking is collecting a diversity of data about users and their online activity across websites, services, and applications. Data are being collected for further utilization and manipulation. Tracking is exactly what used for further ad targeting and hard selling. Mozilla Firefox has its own inbuilt Tracking Protection tool. 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) and press Options;

    • Press the Privacy And Security tab;

You’ll see that Firefox provides a default “Standard” tracking protection that disables social media trackers, cryptominers, and cross-site tracking cookies. To enable full protection you should choose the “Strict” option right under the “Standard”. You should keep in mind that strict protection may crash some websites and ruin your Internet experience, but there’s a workaround.

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.

    • Go to a website on which you want to allow tracking. Click a tiny shield next to the website’s URL. Turn off the Enhanced Tracking Protection for this website and you’re good to go.

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, Strict Tracking Protection enabled on Buzzfeed leaves blank space where banners were supposed to be and also hides a comments section.

To be fair, Tracking Protection is supposed to stop tracking not to stop adverts on Firefox. If you want an ad blocker, use something designed with the express purpose of blocking adverts  AdLock.

Block Ads on Firefox with FlashBlock

Unfortunately, Flash Block is a discontinued extension designed to take control over Adobe Flash-based content including all sorts of commercials, browser games, etc. Of course, you may find third-party resources and download a legacy FlashBlock extension but it’s not guaranteed to work on actual Firefox patches. Also, you may find a Flash Block (plus) that is a replica of that good-ol extension and works pretty similar to it: it disables Flash elements from loading and shows “Flash Content” placeholders instead. If you wish to run loading, click the placeholder to see the original content. FlashBlock was good back then because:

  • It allowed blocking Flash content on all webpages at once;
  • Was quite 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 the web pages will be disabled. Whitelisting and blacklisting in the 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.

How to Disable Ads in Firefox on Android With AdLock

Currently, the Firefox browser on Android dow not allow installing and using third-party certificates, which makes it impossible for AdLock to perform HTTPS filtering on the browser. To admit, HTTPS filtering is the process that is critical for efficient adblocking. Nevertheless, the solution is easy. Mozilla suggests downloading Firefox Nightly which provides this possibility. This means if you prefer using Firefox on your smartphone and wish it to be ad-free, then you need this duo — AdLock and Firefox Nightly.
