Ads and trackers. Portelon blocks ads, trackers and malware on every site, for you and your agents.
It uses the filter lists uBlock Origin uses by default, with the regional ones for your browser’s language, and keeps them up to date.
On a page
The shield in the address bar counts what Portelon blocked on the page. If a site doesn’t work as it should, open the shield and turn off Block on this site. Your agents follow the same setting.
To get rid of something on a page, right-click it. Remove element… removes it until the page reloads; Block element… writes a filter, so it stays gone.
A page blocked as a whole names the list that blocked it, and offers Go back or Open it anyway. For a tracking link, it offers the address the link was on its way to.
Settings
In Settings › Ads and trackers, you choose where Portelon blocks, manage your exceptions and its 71 filter lists, and write filters of your own, in uBlock Origin’s syntax.
