New Tab Override is a Firefox add-on that lets users choose which page Firefox shows whenever a new tab is opened. It can open any website, use the current homepage, display a stored local HTML file, or show a plain background color. It also offers options for focus behavior and tab position, and is available in many languages.
Linkwarden is an open-source, self-hostable bookmark manager that backs up saved pages in multiple formats, including full HTML. It offers a reader view with highlights and annotations, AI-powered tagging, RSS feeds and sharing of collections. A cloud plan is available with a free trial.
Update Scanner is a Firefox addon that monitors web pages for updates, intended for websites that do not provide Atom or RSS feeds. Users can add pages, choose how often changes are checked, and opt to ignore minor updates. Detected changes appear in a notification panel and highlighted in yellow, and updated items are listed in a sidebar.
Auto Tab Discard is a browser extension that automatically discards inactive tabs after a specified amount of time to reduce memory usage and prevent background scripts from consuming computational resources. It uses the browser's native tab discarding method, so discarded tabs are removed from memory but can be restored with their page state, including scroll position. An exception list and tab-type exclusions are configurable.
FoxyLink is a Firefox extension that adds link-related actions to the browser context menu. Its features include opening, copying, or saving selected links, removing duplicate URLs, and grabbing URLs from mixed text and hyperlinks. The developer states the extension contains no tracking, advertising, or privacy infringement.
Hidden Settings is an open source project with code, documentation, and setup resources for browser settings.
SmartUpscale is an extension for Firefox and Chrome that applies integer scaling to images on webpages, preventing blur on images whose displayed size is an integer multiple of their real size. It is aimed at high pixel density displays. The scale is calculated per image, and options and limitations are documented.
