    Privacy Badger

    Privacy Badger

    Privacy Badger automatically learns to block invisible trackers

    Privacy Badger is a browser extension that stops advertisers and other third-party trackers from secretly tracking where you go and what pages you look at on the web. If an advertiser seems to be tracking you across multiple websites without your permission, Privacy Badger automatically blocks that advertiser from loading any more content in your browser. To the advertiser, it’s like you suddenly disappeared. Privacy Badger was born out of our desire to be able to recommend a single extension that would automatically analyze and block any tracker or ad that violated the principle of user consent; which could function well without any settings, knowledge, or configuration by the user; which is produced by an organization that is unambiguously working for its users rather than for advertisers; and which uses algorithmic methods to decide what is and isn’t tracking.

Theme versions compatible with older Firefox releases are preserved as git tags. We also have the beta branch for fixes only applicable to the current Firefox beta version.

    PostCSS

    PostCSS

    A tool for transforming CSS with JavaScript

    PostCSS is a tool for transforming styles with JS plugins. These plugins can do a great number of things: transpile future CSS syntax, lint your CSS, support variables and mixins, and so much more. PostCSS works by taking a CSS file and providing an API to analyze and modify its rules (through its transformation into an Abstract Syntax Tree). The API can then be used by plugins to do a lot of useful things. With PostCSS, you can increase code readability by adding vendor prefixes to CSS rules; convert modern CSS so it's understood by more browsers; and avoid errors in your CSS via stylelint, a modern CSS linter. PostCSS currently has over 200 plugins, and is being used by industry leaders worldwide.

    Replace Google CDN

    Replace Google CDN

    A Chrome plugin: Replace Google CDN with domestic

    For well-known reasons, just substituting a domain name can continue to use the front-end public library provided by Google. Likewise, referencing these resources via the scripttag will instantly speed up your website access! Many websites, especially foreign websites, use Google's CDN in order to speed up the website. But in China, due to some reasons, the world's fastest CDN has become the world's slowest. So, I wrote this plugin/extension to replace Google's CDN with a domestic one. This plugin/extension can replace the cdn resources with domestic ones.

    Web Archives

    Web Archives

    Browser extension for viewing archived and cached versions of websites

    Browser extension for viewing archived and cached versions of web pages, available for Chrome, Edge and Safari. Web Archives is a browser extension that enables you to find archived and cached versions of web pages, and comes with support for more than 10 search engines.

Visit the wiki for the full list of supported search engines. You may choose to allow the extension to run on every website, or grant access to the current website before a search. When you grant access only to the current website, access must also be granted to each search engine in order to view search results. A handful of search modes are offered that serve different use cases. The search mode can be set independently for the context menu and the browser toolbar from the extension's options.

    Librefox

    Librefox

    Firefox with privacy enhancements

    This project aims at enforcing the privacy and security of Firefox without forking the project. Librefox uses more than 500 privacy/security/performance settings, patches, Librefox-Addons (optional) and a cleaned bundle of Firefox (updater, crashreporter and Firefox's integrated addons that don't respect privacy are removed).

IJWY (I Just Want You To Shut Up): embedded server links and other calling home functions are removed (zero unauthorized connection by default). Settings protection: important settings are enforced/locked within mozilla.cfg and policies.json, those settings cannot be changed by addons/updates/Firefox or unwanted/accidental manipulation; To change those settings you can easily do it by editing mozilla.cfg and policies.json.

    JavaScript Cookie

    JavaScript Cookie

    A simple, lightweight JavaScript API for handling browser cookies

    A simple, lightweight JavaScript API for handling cookies which works in all browsers and accepts any character. It is heavily tested, has no dependency, supports ES modules and supports AMD/CommonJS. It is RFC 6265 compliant, has an useful Wiki, and enables custom encoding/decoding. More than 800 bytes gzipped! This project is RFC 6265 compliant. All special characters that are not allowed in the cookie-name or cookie-value are encoded with each one's UTF-8 Hex equivalent using percent-encoding. The only character in cookie-name or cookie-value that is allowed and still encoded is the percent % character, it is escaped in order to interpret percent input as literal. Please note that the default encoding/decoding strategy is meant to be interoperable only between cookies that are read/written by js-cookie. To override the default encoding/decoding strategy you need to use a converter.

    Multi-Account Containers

    Multi-Account Containers

    Keep parts of your online life separated into color-coded tabs

    Firefox Multi-Account Containers lets you keep parts of your online life separated into color-coded tabs. Cookies are separated by container, allowing you to use the web with multiple accounts and integrate Mozilla VPN for an extra layer of privacy. Under the hood, it separates website storage into tab-specific Containers. Cookies downloaded by one Container are not available to other Containers. You can even integrate individual Containers with Mozilla VPN to protect your browsing and location. With the Firefox Multi-Account Containers extension, you can sign in to two different accounts on the same site (for example, you could sign in to work email and home email in two different Container tabs. Keep different kinds of browsing far away from each other (for example, you might use one Container tab for managing your Checking Account and a different Container tab for searching for new songs by your favorite band)

    No Coin

    No Coin

    No Coin is a tiny browser extension aiming to block coin miners

    No coin is a tiny browser extension aiming to block coin miners such as Coinhive. Even though I think using coin mining in browser to monetize content is a great idea, abusing it is not. Some websites are running it during the entire browsing session which results in high consumption of your computer's resources. I do believe that using it occasionally such as for the proof of work of a captcha is OK. But for an entire browsing session, the user should have the choice to opt-in which is the aim of this extension. The idea was to keep it separate from adblocking. Coin mining in the browser is a different issue. Where ads are tracking you and visually interfering with your browsing experience, coin mining, if abused, is eating your computer resources resulting in slow downs (from high CPU usage) and excessive power consumption. You might be OK with that and not with ads, or vice versa. Or you might just want to keep ads blocked entirely and just enable the coin mining script.

    OverlayScrollbars

    OverlayScrollbars

    A javascript scrollbar plugin which hides native scrollbars

    A javascript scrollbar plugin that hides native scrollbars, provides custom styleable overlay scrollbars and keeps the native functionality and feeling. The plugin combines the features of native scrolling (e.g. hotkeys, speed, smoothness, touch support etc.) and custom HTML & CSS. It does not replace the native scrollbars, it just hides them to guarantee 100% native scrolling. It also provides additional and highly customizable DOM elements to style your own scrollbars. To check how flexible the styling is, take a look at the examples in the styling demo. Textarea elements have extended support. Dependent on your options, textures can have dynamic width and height. This means the size of the text area is dependent of its content. For more information please read the documentation to the textarea options or check out the textarea demo. No-auto-wrapping (wrap="off") textures are also supported.

    FastClick

    FastClick

    Easy-to-use library to remove click delays on browsers with touch UIs

    FastClick is a simple, easy-to-use library for eliminating the 300ms delay between a physical tap and the firing of a click event on mobile browsers. The aim is to make your application feel less laggy and more responsive while avoiding any interference with your current logic. FastClick is developed by FT Labs, part of the Financial Times. Note: As of late 2015 most mobile browsers - notably Chrome and Safari - no longer have a 300ms touch delay, so fastclick offers no benefit on newer browsers, and risks introducing bugs into your application. Consider carefully whether you really need to use it. The library has been deployed as part of the FT Web App. FastClick doesn't attach any listeners on desktop browsers.

    Tree Style Tab

    Tree Style Tab

    Tree Style Tab, Show tabs like a tree.

    This extension to Firefox provides the ability to work with tabs as "trees". New tabs opened from the current tab are automatically organized as "children" of the current tab. Such "branches" are easily folded (collapsed) by clicking on the arrow shown in the "parent" tab, so you no longer need to suffer from too many visible tabs. If you want, you can restructure the tree via drag and drop. Such a tree of tabs will behave like a visual browsing history for you. For example, if you see a list of search results for a topic, each search result link will open in new child tab. New tabs opened from these "child" tabs will appear as descendants of their originating tabs. You'll easily dig and dig deeply, without losing your browsing trail - if you want to go back to the original search result, you just have to switch to the "root" tab. Moreover, each tree will reflect a group of tabs on a similar topic.

    jqGrid

    jqGrid

    jQuery grid plugin

    jqGrid is an Ajax-enabled JavaScript control that provides solutions for representing and manipulating tabular data on the web. Since the grid is a client-side solution, loading data dynamically through Ajax callbacks, it can be integrated with any server-side technology, including PHP, ASP, Java Servlets, JSP, ColdFusion, and Perl. Improve the maxGridHeigh method. Add a third parameter to indicate the minimum height at which the method run. jqGrid uses a jQuery JavaScript Library and is written as a plug-in for that package. JqGrid was developed by Tony Tomov at Trirand Inc., a software development firm based in Sofia. Trirand specializes in the development of web components and embraces free and open standards like jQuery, ThemeRoller, & jQuery UI. Tony got the idea for jqGrid when he needed an easy way to represent database information in a project. The first requirement was speed and the second, was independence from server-side technology and the database backend.
