userscripts VS Netflix-Marathon-Pausable

You linked to the Github page, not the script itself: https://github.com/Farow/userscripts/raw/master/reddit-highlight-new-comments.user.js

Add in a few Tampermonkey scripts like highlight-new-comments and Load 'Continue this thread' inline. Next thing you know, the UI is almost not completely horrible.

I use this by Farow. It works with Violentmonkey and Tamper Monkey.

// ==UserScript== // @name Image replacer // @namespace https://github.com/Farow/userscripts // @description Replaces images // @include * // @version 1.0.0 // @grant none // ==/UserScript== let lookup_table = { 'lookup': 'replacement', }; for (let image of document.getElementsByTagName('img')) { for (let query in lookup_table) { if (image.src == query) { image.src = lookup_table[query]; } } }

You can try this: https://github.com/Farow/userscripts/blob/master/reddit-fade-seen-links.user.js

there is another workaround, which involves using javascript to animate the element before it's destroyed. I have some examples of that, not in the firefox UI but in this userscript I wrote for skipping ads/credits/intros on netflix. it has a settings UI that fades in as it's created, and fades out as it's destroyed. the way I worked around the issue is to not actually destroy it immediately when the user closes it. instead the destroy function immediately sets a closed attribute on the UI frame. then the CSS has a rule like frame[closed] { opacity: 0; pointer-events: 0; transition: 500ms opacity ease-in-out; } or something like that.
