How to kill ads on Huawei Mate 10 Pro without Rooting the phone

What does the good people of XDA think is the way to go to kill ads without rooting?

NB: These tips and tricks are not my brain work. It is a collection of problems, issues and solutions to things I've experienced with the Mate 10 Pro, and the solutions are the great work of this forum and various contributors. My only contribution is to try to gather them all here in post one so people don't need to read the whole thread. In particular i would like to thank Pretoriano80 for his contributions in this thread. He made my life easier. Thank you.

Recap:

Remove Ads from browsers:

This solution worked well for removing ads from browsers, so I bought it from playstore to show my support. Thx to Pretoriano80 for resolving most of my ad problems.

This solution also takes care of the in-apps ads!

Youtube without ads:

A youtube version that is slightly altered to filter out ads. Works on non rooted devices and can be installed alongside the original youtube. Notice the modified MicroG apk on the second quote for using this modified youtube with your google account.

Huawei Mate 10 Pro apps loosing 4G and Wifi connection

When I first started to use the Huawei Mate 10 Pro I noticed that every once on a while an app would not work when I tried to restart the app. Suddenly I got an error saying their was no data connection, meaning no 4G or wifi. It was faulty error because I could use data in other apps. For me typically the problem was related to Spotify and Audible. The only fix I could find right away was a full reboot. It always took care of the problem and apps would work properly. Reboots are not welcome in a busy day. So I've looked around and found that I could manually control the power saving management for each app in >setting>battery>Launch. By taking back the control apps worked flawless once again.

A few weeks ago we had a yet another firmware update. And behold, once again the problem started. Only this time even in manual mode in >Launch the apps would still loose their 4G connection randomly, or even wifi if at home. It seemed like a reboot was the only choice to get things working. Until I by pure luck tried to enable the Ultra Battery Saver from the pull down menu. Enable it, then exiting it somehow resolves any power saving issues. Apps they work fine, they get their data connection, both 4G and wifi. The quick fix takes only seconds to complete, and there is no need to do a full reboot in order to have apps fully working.
