Adds a search bar to the Favorites page
This script adds a search bar to the Favorites page. It allows you to search your favorites with different options, even just by part of a tag.

When the search is complete, all results are displayed on the same page. You can click on any image to open the original post, randomize the order of images, sort by score and other sorting options, or remove some images from your favorites.

Highlights images with a red border on other pages of the site if they are already in your favorites.

The UI has also been optimised for mobile devices. You can use it with Tampermonkey for Firefox Mobile or other browsers supports userscripts.
Additional information and instructions can be found in the script's Help & Info menu.
If you have some questions or suggestions, you can visit the project's Discord. You can also find some other useful scripts for Rule34 there.
