My Opera built-in adblocker is not working (particularly on YouTube)... There are still ads, or there is a white screen instead of the video ads.
It might be caused by a problem of lists. The ad lists are what we call "rules" for the adblockers. When the adblocker detects something which is on the list, it automatically removes them from the HTML code of the page
(the HTML code is a bit like the words that make up a book: HTML makes up the web page... It contains all the information that the browser (Opera) must display).
But advertisers are really smart and they create new rules, new codes to avoid adblockers every day.
That's why adblockers update their lists every day. This action is usually done automatically but you might need to do it manually sometimes, especially when you're seeing ads despite having adblocker enabled.
Here's how you do that:
1 - Go to opera://settings/adBlockerLists
2 - Click on Update lists
3 - Restart your browser.
This is not guaranteed to work every time and if it doesn't work, we recommend you to install uBlock Origin and use that for the time being.
How to update uBlock Origin's lists:
1 - Go toopera://extensions
2 - Find uBlock Origin
3 - Click on Options
4 - Go into filter lists
5 - Click on update now and wait a bit.
6 - Check if it worked.
Note::
Do** NOT** use more than one adblocker at the same time, doing so will cause issues such as the browser working extremely slow.
Only select the recommended lists as they are chosen based on the sites you browse on. Do not choose extra lists, there is no such thing as
more lists = more ads blocked.
