About LemmyTools
LemmyTools is a Firefox extension that adds utilities for using Lemmy sites. It provides a searchable bar for subscribed communities with grouping and sorting, plus user tagging, keyword-based hiding of posts and comments, image resizing and display controls, sidebar hiding, and link-opening options.
The repository now ships only the Firefox add-on under extension/; the earlier Greasemonkey/Tampermonkey userscript is retired. Settings are stored in browser.storage.local and are applied across open Lemmy tabs without requiring a reload.
