##### uBlock Tips

- Before creating a filer, check if you can fine-tune the rule, e.g. adding a wildcard `*` might make it more generic, or blocking a whole domain instead of a subdomain
- `domain##div>a:has-text(/promoted post/)`: At `domain`, remove any `<div>` containing a link with text `"promoted post"`.
- `##[data-testid="AAA"]`: Remove any element with a `data-test` id attribute with value `AAA`.
- [basic filtering syntax](https://github.com/uBlockOrigin/uBlock-issues/wiki/Introduction-to-basic-filtering-syntax)
