uBlock Origin allows you to filter custom elements on webpages. I can zap those elements and next time I visit that site I won't have to put up with it. It's game-changing although I wish there was a way we could share custom filters with others so I don't have to do this for every site each time

Oh, but there is a way to "share custom filters with others" :) https://github.com/gorhill/uBlock/wiki/Filter-lists-from-aro...

There is also a cool site that aggregates custom lists and allows you to search for specific filter-lists and narrow down choices by using filters on top. You can then subscribe to them directly - most are hosted on github. Just keep in mind some of them haven't been updated in years - you can preview them, and check their last update - in most of cases anyway. https://filterlists.com/

BTW there are filters specifically designed to remove newsletter-signup messages, popups, popunders, as well as general "annoyances" :)

do you have the Annoyances filters enabled? most of them are filtered on my end

there is also this you can enable with 1 click if you've got ublock already: https://github.com/yourduskquibbles/webannoyances
