Making the internet more tolerable
Filter allows you to create custom text replacements for the internet. For example, change every instance of "Moar" to "More" or "My ex's name" to "Some slimebag". Update your filters through a friendly interface, search them or change them without even having to click a 'save' button. It also allows you to target specific CSS selectors for removal that more UI-intensive ad blockers might not be able to target. And lastly there's a spot to inject your own custom JS on every page.
