Reddit NSFW Blur Toggle

WHAT IT DOES

Reddit NSFW Blur Toggle is a browser extension that automatically scans the current Reddit page for NSFW posts, NSFW tags, and blurred content indicators. It detects NSFW elements by examining class names, IDs, and text patterns for keywords like "nsfw", "blurred", and content warning indicators. The extension adds a floating toggle button (🔞) next to the Reddit interface, providing quick access to NSFW blur controls. Clicking the button opens a panel where you can toggle NSFW blur on or off, set default blur state per subreddit, and store preferences locally. The panel displays the current subreddit, number of NSFW elements found, and current blur status. You can enable or disable blur globally, apply blur immediately, and save subreddit-specific preferences (Blur NSFW, Show NSFW, or Use global setting). The extension maintains an NSFW blur preferences database with settings history, notes, and tags. The main panel shows saved preferences for the current and recent subreddits. All data is stored locally in your browser using GM_setValue, ensuring your preferences persist across page reloads and browser sessions. This helps Reddit users who want to manage NSFW content visibility, toggle blurring quickly, and maintain different preferences for different subreddits.

WHERE IT RUNS

This extension runs on any Reddit page that displays NSFW posts, NSFW tags, or blurred content indicators – including Reddit front page, subreddit pages, and any page with NSFW content. The extension intelligently adapts to different page structures and supports a wide range of common Reddit display patterns. No manual configuration is required per site; the extension automatically detects NSFW elements using a flexible pattern matching system. This makes it ideal for Reddit users who want to manage NSFW content visibility.

HOW TO USE

Simply install the extension and navigate to any Reddit page with NSFW content. The extension automatically detects NSFW elements and shows a toggle button (🔞) next to the interface with a status indicator. Click the button to open the NSFW blur panel. The panel shows the current subreddit, the number of NSFW elements found, and the current blur status. Toggle "Enable Blur" to turn blurring on or off globally. Click "Apply Blur Now" to apply the current setting, or "Remove Blur Now" to clear all blurring. For subreddit-specific preferences, select "Blur NSFW", "Show NSFW", or "Use global setting" from the dropdown to save your preference for that subreddit. A floating button (🔞) appears in the bottom-right corner of the page – click this to open the panel from anywhere. Use the notes section to add notes about content preferences or viewing habits. The panel also shows saved preferences for the current and recent subreddits. Use the "Clear All Data" button to remove all tracking data when needed.

ONE TECHNICAL SECTION – WHY IT WORKS

The extension uses a combination of DOM detection and CSS styling to toggle NSFW blur. The NSFW element detection uses a comprehensive set of CSS selectors targeting NSFW indicators including ".nsfw", ".NSFW", ".blurred", ".blur", and text-based detection on post titles containing "nsfw". The extension also detects NSFW tags and content warnings. When blur is enabled, the extension applies a CSS filter with blur(8px) to all detected NSFW elements, along with user-select: none and pointer-events: none to prevent interaction. A hover effect removes the blur when the user hovers over the element, providing a preview without permanent unblurring. The extension also targets child elements like images and videos within NSFW containers. Each NSFW element is tracked with a class name for consistent styling. The blur state can be overridden per subreddit with preferences stored in the local database. A MutationObserver detects dynamic content updates and re-scans only when new NSFW elements appear, balancing real-time accuracy with system performance.

THE PANEL – DRAG / PER-SITE POSITION / SNAP / COLLAPSE / RESIZE / ESCAPE

The NSFW blur toggle panel includes a draggable title bar, allowing you to position it anywhere on screen for convenient access during browsing. The extension remembers your preferred position per website, so the panel opens in the same location each time you return to that domain. The panel supports snap-to-edge behavior – when dragged near screen edges, it gently snaps into place for a tidy workspace layout. You can collapse the panel down to just its title bar by clicking the collapse button, keeping it accessible without taking up screen space. The controls and settings are contained within a scrollable body, ensuring all content remains accessible even on smaller screens. Pressing the Escape key closes the panel instantly, returning you to your Reddit browsing workflow.

PLEASE NOTE

This extension requires the free BotGentz extension to be installed and enabled, as it relies on BotGentz's userscript injection and GM_* API shims for cross-browser compatibility. Websites frequently update their HTML structures and class names, which may cause NSFW detection to break temporarily – we actively maintain the matching patterns and release updates regularly. The extension stores all NSFW preferences, notes, and history exclusively in your local browser storage (GM_setValue); no data is ever transmitted to any external server or third party. The extension does not read, modify, or interfere with any Reddit content or functionality beyond the display – it operates on the page content and stores only metadata (subreddit names, blur preferences, and notes) that you explicitly create. You are responsible for backing up your preference data if you switch browsers or clear your storage. Use this tool responsibly and in accordance with Reddit's Terms of Service.
