The internet is unusable without uBlock Origin.
The first extension I install in a browser.
Blocks ads, trackers and anything else you want.
Read the documentation before using.
Using in in conjunction with adguard system-wide.
Using other blocker extension with uBO such as (adblock, abp, etc) could lead to problems !
If uBo is too hard to use for you then adguard extension is a good alternative (but uses ~x4 more ram)
