Filter Reddit feeds in Firefox with targeted hiding tools
Ultimate Reddit Filter, created by Script Smith, is a Firefox extension that helps users reduce unwanted Reddit content and spoilers through client-side filtering. The extension hides posts by subreddit, blocks posts and comments from specific users, and filters titles and linked domains. A simple dashboard and a global enable/disable switch manage active rules. The tool is aimed at frequent Reddit readers who want a lower-noise browsing session without heavy add-on complexity.

How the extension reshapes your Reddit feed
The extension removes undesired items before they clutter the page, giving control over what appears in feeds and comment views. It provides multiple filter types, including:
Subreddit filtering: hide posts from specific communities
User blocking: remove posts and comments from named accounts
Keyword/title and domain filters: block posts by words in titles or by linked sites
These rules are edited in a concise management interface so lists stay organised.
How private is your browsing after applying filters?
The extension focuses on reducing exposure to spoilers, toxic communities, and repetitive content by hiding items in the browser view, which changes what you see while browsing Reddit. Script Smith describes the developer intent as improving user agency and content moderation, and the design emphasises in-extension control rather than altering your Reddit account or server-side feeds. The filtering acts on visible posts rather than on account-level moderation tools.
Does the extension fit across desktop Firefox installations?
The tool is distributed as a Firefox browser extension for desktop platforms (Windows, macOS, Linux) and is optimised for that environment. It is described as lightweight and tuned to avoid slowing page load times. Compatibility targets the standard Reddit interface, so users should keep the extension current to maintain behavior when Reddit changes its layout. The extension suits desktop-centric browsing rather than cross-browser or mobile workflows.
Practical choice for desktop Reddit users who want tighter in-browser control
Ultimate Reddit Filter is a pragmatic option for frequent Reddit readers who need precise, in-browser feed control. A clear constraint is its Firefox desktop scope, which narrows applicability for users who rely on mobile apps or other browsers. For those who prefer local, low-footprint moderation of what appears while they browse, the tool fits well as a focused content-reduction solution.
