Safari lag on macOS Mojave

Hi dear community!

I have a brand new MacBook Pro 13" (no Touch Bar) with 16Gb of RAM and I'm having a bad experience with Safari: it lags and cause high CPU usage in particular while visiting Amazon and YouTube (not while watching video, but in the search bar in particular .. is a pain!).

Again, the computer is brand new, fresh installed and no particular 3th part app. Safari has the following extension enabled:

ABP Control Panel
ABP

Basically just Add Blocker Plus.

I have already cleaned history & cache but no result, same stuff after deleting the content of ˜/Library/Safari. What else can I check/do?

Remove the ABP Control panel and extension. Quit Safari and other open applications. Press and hold the shift key when you reboot to venture into Safe Boot mode. Look in your local Library Caches folder for any folder name containing the "safari" string. Drag just these items to the Trash, and reboot normally. After the reboot, empty your Trash, and see if Safari behaves better visiting Amazon or Youtube.

In the Mac App Store, there is a 4.5 star rated, free Ad and Stuff Blocker that I use. It downloads an application, that when run from Launchpad, installs the Safari extension. In use, this ad blocker does a remarkable job without impacting browser performance. Using with Safari 12.0.2 on High Sierra 10.13.6 and Mojave 10.14.2.
