Notes:
Port numbers in computer networking represent communication endpoints. Ports are unsigned 16-bit integers (0-65535) that identify a specific process, or network service. IANA is responsible for internet protocol resources, including the registration of commonly used port numbers for well-known internet services.
Well Known Ports: 0 through 1023.
Registered Ports: 1024 through 49151.
Dynamic/Private : 49152 through 65535.
TCP ports use the Transmission Control Protocol, the most commonly used protocol on the Internet and any TCP/IP network. TCP enables two hosts to establish a connection and exchange streams of data. TCP guarantees delivery of data and that packets will be delivered in the same order in which they were sent. Guaranteed communication/delivery is the key difference between TCP and UDP.
UDP ports use the Datagram Protocol. Like TCP, UDP is used in combination with IP (the Internet Protocol) and facilitates the transmission of datagrams from one computer to applications on another computer, but unlike TCP, UDP is connectionless and does not guarantee reliable communication; it's up to the application that received the message to process any errors and verify correct delivery. UDP is often used with time-sensitive applications, such as audio/video streaming and realtime gaming, where dropping some packets is preferable to waiting for delayed data.
When troubleshooting unknown open ports, it is useful to find exactly what services/processes are listening to them. This can be accomplished in both Windows command prompt and Linux variants using the 'netstat -aon' command. We also recommend runnig multiple anti-virus/anti-malware scans to rule out the possibility of active malicious software. For more detailed and personalized help please use our forums.

As a blogger myself, I support online ads and strongly feel that some unobtrusive, useful ads that don’t interfere with your online activities are useful for publishers. For most of us here, it’s the only source of daily bread and butter. But then, there are some websites that bombard you with ads and at the same time, block your access if an ad-blocker is detected.

Premid home

So today, I will demonstrate how you can whitelist websites (like ours) which are reasonable about putting ads and at the same time show you a simple trick using which you can bypass the ad blocker check imposed by many websites.

Whitelisting Websites on Ad Blocker

Firefox

It’s a wise thing to do by whitelisting a useful website on ad blocker, one which gives sensible ads that don’t obstruct your work. To get that done, simply open the website and then click on the ad-blocker plugin on the browser. Here, select the option Don’t run on pages of this domain. The plugin will then allow ads on the current website and block on others. So go ahead and try it out.

Easy One-click Solution to Bypass Ad Block Detection

Premid App

The easiest way you can bypass ad block detection on a website is by disabling JavaScript using the Site Info option on the browser. Just click on the Site Info icon as shown in the screenshot and disable the JavaScript option.

The option will bypass the ad blocker for the particular website but this will also cause other JavaScript to be disabled as well. So if you are visiting the website for reading purpose, it would be just fine. However, if there are some important elements that require JavaScript, it will be missing from the page and that may confuse you.

Bypass Adblock Using Tamper Monkey Script

If there are more than one website you wish to bypass, than installing anti-adblock killer makes more sense. The UserScript helps you keep your ad-blocker active when you visit a website even when it asks you to disable it. As this is a script, you will have to install Greasemonkey on Firefox or Tampermonkey for Opera or Chrome. Once these add-ons are installed, you will have to Subscribe to Filter List for the specific ad-blocker you are using on your browser.

Having done all that, install the Anti-Adblock UserScript and re-launch the browser for the changes to take effect.

Well, that’s about it. The script will automatically detect the websites that are trying to block your ad-blocker and will bypass them easily, without you even having to raise a finger. However, you should be informed that this is not a universal solution and might not work on all the websites that use anti ad-blocker.

Conclusion

So that how you can bypass ad blocking blockers on almost all the websites out there. The trick works on Firefox, Chrome, Opera and Safari with supported ad-blockers like Adblock, Adblock Plus, uBlock Origin, and Adguard AdBlocker. So try it out and let us know which one works best for you. Also, please don’t forget that these ads are necessary for the free content that we publish and therefore you should think twice before blocking ads on a particular website and go ahead only if it’s extremely annoying.
