Rexplorer: Reddit & Instagram Media Gallery by Anson Alexander

Rexplorer turns Reddit and Instagram into fast, visual media galleries for photos, GIFs, videos, Reels, and image collections.

Instead of opening posts one by one or scrolling through long feeds, Rexplorer organizes media into a clean masonry gallery. See more at once, open what catches your eye, and move through photos and videos with fullscreen viewing, zoom, and slideshow controls.

Whether you're browsing image-heavy subreddits, exploring Instagram creators, watching Reels, or looking for a better Reddit image viewer, video viewer, or slideshow, Rexplorer brings those experiences together in one Firefox add-on.


• Fast masonry-style media galleries for Reddit and Instagram
• Browse photos, GIFs, galleries, videos, and Reels
• Focused media viewer with zoom, pan, and fullscreen
• Adjustable zoom slider and built-in slideshow
• Keyboard, mouse-wheel, click, and on-screen navigation
• Touch-friendly controls on supported devices
• Filter by Images, Videos, or All
• Remember your layout, filters, and preferences


Turn subreddits, Reddit profiles, and your Home feed into visual media galleries.

• Browse Reddit images, GIFs, multi-image galleries, and videos in one grid
• Watch native Reddit videos, with audio when available
• Portrait and landscape video playback
• Support for RedGIFs, Imgur GIFV, YouTube, Vimeo, and compatible media links
• Sort by Hot, New, Top, Rising, Best, and Controversial, with available time ranges
• Hide individual posts or show hidden posts again
• Navigate image galleries and slideshows without repeatedly opening posts
• Pro: Watchlist, dedicated Watchlist feed, and Turbo Mode


Explore Instagram photos, videos, carousels, and Reels using the same Rexplorer gallery experience.

• Browse your Instagram Home feed and public profiles
• Explore profile Reels tabs and the Reels feed
• View supported keyword search results
• Open individual posts and Reels
• View full-resolution photos and navigate carousel slides
• See who posted each photo or Reel, with its hashtags and caption
• Watch supported videos and Reels in the media viewer
• Automatically load more posts as you browse, or choose manual loading
• Open the original Instagram post whenever needed

To start on Instagram, click Rexplorer in the Firefox toolbar and choose Open gallery. Firefox asks once for access, the gallery opens, and the floating Rexplorer button appears on supported pages from then on.

Instagram Explore and Stories aren't currently supported. Rexplorer works with content available to your Instagram account.


Rexplorer Free includes the core gallery and viewer experience on both Reddit and Instagram.

• Browse up to 150 posts per feed
• No daily browsing cap
• Photos, GIFs, videos, carousels, and Reels
• Fullscreen, zoom, and slideshow controls
• Media filtering and navigation
• Saved layouts and preferences

Each carousel or Reel counts as one post.

1. Install Rexplorer in Firefox.
2. Open a Reddit or Instagram page.
3. Click the floating Rexplorer button on a supported page.
4. Browse the gallery, open media, and navigate with the viewer.

For Instagram, choose Open gallery from the Rexplorer toolbar button and allow access when Firefox asks. For Reddit, signing in generally provides more reliable access to full feeds.

Rexplorer organizes media from the pages you already browse. It doesn't post, vote, like, follow, or send messages on your behalf.


Rexplorer is designed to keep normal browsing data local.

• No separate Rexplorer account required
• No behavioral advertising by Rexplorer
• Favorites, hidden posts, Watchlist entries, and preferences stay in your browser
• Reddit and Instagram browsing history, gallery contents, and saved posts aren't sent to Rexplorer's licensing server

For Pro activation and validation, Rexplorer sends your license key to its licensing service. If you grant Firefox's optional technical-data permission, it also sends a randomly generated installation ID, browser family, and Rexplorer version.

The installation ID isn't derived from your device hardware.
