Reddit Slideshow Spectacular!

By: Rio517 Add-on
Turn your old or new Reddit feeds into a full-screen, keyboard-driven media slideshow. Free, Private, Local, No Tracking.

Features & Capabilities

Reddit Slideshow Spectacular! turns your Reddit feeds into full-screen, keyboard-driven media slideshow. Open a feed, subreddit, multireddit, or search results on old.reddit.com or www.reddit.com, click the toolbar icon (or press Alt+Shift+S), and lean back.

The Slideshow reuses your existing logged-in Reddit session - no API keys, no sign-in, no extra account. It walks media posts in the order Reddit returns them and pages through the feed automatically, so the slideshow keeps going past the first page.

WHAT'S NEW - V1.2.0

  • New keyboard shortcuts: D to download the current image or video, I to block the author (and skip their post), and A to friend/follow the author
  • Separate "always show the count & skips" and "always show the title & byline" toggles
  • A quieter position counter and skipped-count badge, with a small corner spinner while the next slide loads
  • Fixed: the controls now hide when idle even after you click one with the mouse

WHAT IT PLAYS

  • Direct Reddit images (full-resolution i.redd.it where available)
  • Reddit galleries, expanded into one slide per image
  • Reddit-hosted video (v.redd.it), with its sound (the separate audio track)
  • Redgifs, Imgur (.gifv), Streamable, and Giphy clips, played as native video
  • Imgur albums, expanded into one slide per image
  • Catbox video and image files
  • Crossposts, resolved to the original post's media
The queue is media-only: text/self posts, outbound article links, stickied announcements, and promoted/ad posts are skipped, and media that fails to load is skipped too - so the slideshow never lands on a dead slide.

CONTROLS

  • Keyboard: Left/Right to move (Shift+Right skips to the next post; Page Up/Page Down jump back/ahead 10), Up/Down to upvote/downvote the post, Space to play/pause, M to mute, F for fullscreen, D to download, I to block the author (and skip their post), A to friend/follow the author, Esc to close
  • An on-screen control rail: previous, play/pause, next, mute, fullscreen, open in a window, and settings
  • Under each slide: a byline (who posted it, to which subreddit, the source and resolution), with buttons to open the original post or download the media
  • Click the position counter to jump straight to any post in the loaded queue
  • Click the dark backdrop to close
  • Images advance on a timer you set; the timer keeps running even after you arrow through manually, and videos advance when the clip ends
NICE TOUCHES
  • Slide transitions: fade, slide, push, zoom, flip, or none
  • Optional top countdown timer bar (on video slides, every slide, or never)
  • Optional slow pan & zoom for images too big to see at once
  • A pinned position counter and post title so you always know where you are
  • "Open in a window" reopens the slideshow in a minimal popup window, ready to AirPlay or Chromecast to a TV or second screen for a lean-back, big-screen feed
  • Duplicate skipping: reposts, crossposts, and repeated galleries are skipped, and a perceptual hash (on by default) also catches the same image re-uploaded under a new link - solo vs. in a gallery
  • "Open original" jumps to the source post
SETTINGS (apply live, no reload)
  • Time per image (1 second to 5 minutes, on a fine-at-the-low-end scale)
  • Slide transition
  • Timer bar visibility
  • How long to wait for slow media before moving on
  • Autoplay videos on/off, start muted on/off
  • Include NSFW - by default follows your Reddit session, showing over-18 content only insofar as your account already does
  • Skip duplicate media, including re-uploaded images (on by default)
  • Pan & zoom large images (or all images), with full control over the sequence
PRIVACY

No analytics, no tracking, no ads, no accounts, and no developer servers (there are none). The extension only fetches the media you're viewing: the feed and its media from Reddit, and provider clips from Imgur, Redgifs, Streamable, Giphy, and Catbox. The only things that write to your Reddit account are voting (up/down keys), blocking an author (I), and friending/following an author (A) - each only when you press its key. Your settings are stored locally on your computer, and it ships no remote code. Full policy: see the privacy policy link.

Is Reddit Slideshow Spectacular! Safe?

Risk impact
Risk impact measures the level of extra permissions an extension has access to. A low risk impact extension cannot do much harms, whereas a high risk impact extension can do a lot of damage like stealing your password, bypassing your security settings, and accessing your personal data. High risk impact extensions are not necessarily malicious. However, if they do turn malicious, they can be very harmful.

Reddit Slideshow Spectacular! requires some sensitive permissions that could impact your browser and data security. Exercise caution before installing.

Risk likelihood
Risk likelihood measures the probability that a Firefox add-on may turn malicious. This is determined by the publisher and the Firefox add-on reputation on Firefox Add-ons Store, the amount of time the Firefox add-on has been around, and other signals about the Firefox add-on. Our algorithms are not perfect, and are subject to change as we discover new ways to detect malicious extensions. We recommend that you always exercise caution when installing a Firefox add-on.

Reddit Slideshow Spectacular! is recently added, and hasn't been around long enough for us to gather enough data to accurately assess its risk level.
