Related issue: https://github.com/uBlockOrigin/uBOL-home/issues/325 This is a first version, with support only for custom filters which are plain CSS selectors. Future versions will extend support to style-based and procedural cosmetic filters. Manually text-editing existing custom filters is currently not supported, this will be added in a future version in the Develop pane. To remove existing custom filters, the "Remove a custom filter" tool can be used.
