 * For a start, what a great plugin. For now the only problem I accidentally bumped
   into is Firefox.
 * The setup is a query loop which returns 12 posts (custom post type) and displays
   them with a custom layout. I want to use your plugin to make it possible to slide
   through the posts. I tested it in different browsers and on my mobile (chrome
   and duckduck) and until now it works everywhere except in Firefox.
 * What it should look like and looks like in many browsers:

 * What Firefox returns (the queryloop results in 12 posts):

 * Is there a solution to this problem or something I can do? Firefox has no extensions
   installed. And I would really like to use this plugin.
 * best regards Marie-Anne

 * Hello Marie-Anne, Thank you very much for your message. 
   Yes, the plugin uses
   an experimental feature called ::scroll, which is not yet supported by Firefox
   and Safari. [https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::scroll-button#browser_compatibility](https://developer.mozilla.org/en-US/docs/Web/CSS/Reference/Selectors/::scroll-button#browser_compatibility)
   I initially thought of using this new feature, expecting it to be supported by
   all modern browsers soon, but in reality, it still isn’t, and no future compatibility
   date is planned at the moment. I’m planning to change the plugin’s functionality
   to revert to a more classic JavaScript carousel, which guarantees compatibility
   with all browsers. This is a significant change that will require some development
   time. Therefore, I can confirm that I will implement this change, but I can’t
   give you a precise date at the moment. Thank you very much for your understanding.

 * Hi Arthur,
 * thank you for your fast reply. I am a bit disappointed since this is exactly 
   what I need (or my customer) but I understand the significant change (asked Claude
   what the options were to solve this) and serious development time. And if had
   read the reviews better, I could have known :-), but than I would have missed
   the experience, which I really like.
 * I hope you’re talking weeks and not months, Marie-Anne

 * Hi Marie-Anne,
 * I have some absolutely wonderful news for you! Instead of weeks or months, **
   it only took a few days!** 🚀
 * I am thrilled to let you know that **version 2.0.0** is officially live and available
   for update right now in your WordPress dashboard.
 * I have completely refactored the plugin’s architecture to solve this exact issue:
    1. **Full Browser Compatibility**: We have completely removed the experimental 
       CSS `::scroll-*` pseudo-elements and replaced them with standard, native HTML
       navigation buttons and pagination dots. The plugin is now **100% compatible 
       with Firefox, Safari, Chrome, Edge, and all modern mobile and desktop browsers**.
    2. **Lightweight & Fast**: Instead of loading heavy third-party libraries (like
       Swiper or Slick), the controls are powered by a super-lightweight, vanilla JavaScript
       script (less than 5KB) combined with native CSS `scroll-snap`. Your excellent
       Lighthouse and Core Web Vitals performance scores remain completely untouched!
    3. **Improved Editor Experience**: You will also see the navigation arrows and 
       interactive pagination dots directly inside your Gutenberg editor exactly like
       on the frontend, with computed padding detection.
    4. **Interactive Dot Tracking**: Clicking the pagination dots will slide to the
       corresponding post, and the active dot is synchronized in real-time as you scroll
       thanks to a lightweight `IntersectionObserver`.
 * You can simply update **Any Block Carousel Slider** to **version 2.0.0** directly
   from your WordPress updates page, and it should work instantly on Firefox!
 * Thank you so much for your patience, your kind words, and for giving me the motivation
   to speed up this major milestone. Let me know if everything works perfectly on
   your end!
 * Best regards,
   Arthur
