Have problems with your current version of Opera? Download the latest version from the official websiteAlthough many possible causes lead to issues with your Opera browser, one of the fastest solutions is to first reinstall your browser. We do not recommend downloading Opera from any 3rd party source unless it is verified, as you risk getting malware and all types of errors because of it.
Here's what Opera can do:

  • Optimize resource usage: your RAM memory is used more efficiently than in other browsers
  • Enhanced privacy: free and unlimited VPN integrated
  • No ads: built-in Ad Blocker speeds up loading of pages and protects against data-mining
  • Gaming friendly: Opera GX is the first and best browser for gaming
  • Download Opera | Opera GX

Although some people don’t really have a problem with random ads going off while they’re watching videos on YouTube, most just hate the idea of it.

Nothing is simpler than using a block extension or just enabling the ad-block option built in the browser you are using, in order to bypass the constant stream of commercials.

The easiest way to get rid of these pesky ads is to simply install one of the popular ad-blocking add-ons, available for every browser. Once you enable the extension on your browser, the nightmare will be officially over.

Why is Opera GX Adblock not working on YouTube?

Users have taken to discussing this recurring issue on the Opera forum. Many of the complaints are centered around the fact that, because it’s been happening for so long, they expected it to be fixed already.

Neither Opera nor Opera GX are blocking the ads on YouTube properly! I just don’t understand that they can’t fix it for so long, although there was no problem before.

The ad-blocking software seems to have a mind of its own and displays some pretty erratic patterns when trying to do its job.

It blocks one ad, then allows the other nine or ten ads to play, or it loads the ad and it skips it in a split second. Another example is the ad doesn’t start playing, users are just left with a white screen.

Some of the reasons include:

  • Conflicting Adblockers – This can happen if your browser has multiple Adblock extensions or plugins installed. You need to disable similar extensions and try again.
  • Outdated extension – If your Adblock has been working fine but suddenly stops, it could be because it is missing a few critical updates. Check from the Opera Addons page and update accordingly.
  • Virus infection – If you have a virus infection on your computer, then your Opera GX Adblock may stop working as intended due to an issue with your antivirus software interfering with its functionality.
  • Insufficient memory – Another common reason why Opera GX Adblock might not work properly is if there is insufficient memory available on your computer. This could be caused by certain programs running in the background using up all available RAM.

If any of these are the cause of the issue, proceed to the below troubleshooting steps.

Quick Tip:

If the problem persists, giving the browser a good old reinstall could save you the pain.

Since Opera GX comes with preinstalled ad blocker and other features, the problem might be caused by an update error or incompatibility that should go away with a fast reinstall.

How do I fix Opera GX’s Adblock if it doesn’t block YouTube ads?

1. Reinstall the Adblock

The Adblock could be corrupted so you need to reinstall the Adblock extension from the extensions page. If you already had it installed and it’s not working, uninstall it first and then reinstall it again.

If your problem persists after reinstalling the extension, try disabling all other extensions and restarting Opera GX.

2. Scan for malware 

  1. Press the Windows key, search Windows Security and click Open.
  2. Select Virus & threat protection.
  3. Next, press Quick scan under Current threats.
  4. Wait for the process to finish and restart your system.

3. Free up disk space

It’s possible that you have a lot of files stored on your device’s storage and you are running out of space. If you have downloaded many apps and games that use more storage than expected, you can clear space by deleting files that you don’t need.

There are many ways to free up space so try the easiest methods first while trying the extension and see if it works. If the issue persists, you should try and reset your browser or use an alternative browser.

What is the best Adblock for Opera GX? 

Opera GX is a web browser with the ability to block ads. It offers a lot of features such as ad blocking, free VPN, and other cool features.

However, if you are not satisfied with the built-in Adblock, there are many extensions available for Opera which can block ads and help you to surf the internet faster.

There are a lot of ad blockers on the market, but only a few are worth using. The others are either too complicated or have more than enough bugs to make it hard to use them.
