Available for install from the homepage or from the App Store. Available on the Firefox Add-ons site, or for manual installation. Opera shares Chrome's underlying engine, so you can install uBlock simply by grabbing the latest release for Chrome.To benefit from uBlock's higher efficiency, it's advised that you don't use other blockers at the same time (such as AdBlock or Adblock Plus). uBlock will do as well or better than most popular ad blockers. It's important to note that blocking ads is not theft. Don't fall for this creepy idea. The ultimate logical consequence of blocking = theft is the criminalisation of the inalienable right to privacy.

    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.

    Edge Translate

    Edge Translate

    A translation extension

    Edge Translate is a simple and practical translation plugin that supports mainstream browsers such as Chrome, Firefox, and 360 Secure Browser. The main purpose of our plugin is to assist users in reading foreign literature. To this end, we have followed the principle of the user's reading experience first, and made the following efforts. We use the API provided by Google Translate to translate words and sentences, which guarantees the accuracy of translation results to a certain extent. We support the translation of wording in PDF files, which breaks the dyslexia of many users when reading PDF documents (due to the Firefox browser's bug, this feature is temporarily unavailable on Firefox browser). We chose the friendly side pop-up to show the translation results. The pop-up display bar will push the user reading content to avoid blocking the content from affecting the reading. Please refresh the page that needs to be translated after installation or update!

    I Still Don't Care About Cookies

    Debloated fork of the extension "I don't care about cookies"

    Debloated fork of the extension "I don't care about cookies". Get rid of cookie warnings from almost all websites!

The EU regulations require that any website using tracking cookies must get user's permission before installing them. These warnings appear on most websites until the visitor agrees with the website's terms and conditions. Imagine how irritating that becomes when you surf anonymously or if you delete cookies automatically every time you close the browser. This add-on will remove these cookie warnings from almost all websites! You can report any website which still warns you about cookies: just click 'Report a cookie warning' from the extension menu (the brown cookie image next to your address bar).

    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.

    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.

    jqGrid

    jqGrid

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.

    Masonry

    Masonry

    A cascading grid layout plugin

    Masonry is a JavaScript grid layout library. It works by placing elements in optimal position based on available vertical space, sort of like a mason fitting stones in a wall. You’ve probably seen it in use all over the Internet. All sizing and styling of items is handled by your own CSS. tem sizes can be set with percentages for responsive layouts. With the masonry layout mode, set percentage-width columnWidth with element sizing. Set percentPosition: true so item positions are likewise set with percentages to reduce adjustment transitions on window resize. Unloaded images can throw off Masonry layouts and cause item elements to overlap. imagesLoaded resolves this issue. imagesLoaded is a separate script you can download at imagesloaded.desandro.com. Or, initialize Masonry after all images have been loaded.

    eslint-plugin-vue

    ESLint plugin for Vue.js

    ESLint plugin for Vue.js. This plugin allows us to check the template and script of .vue files with ESLint, as well as Vue code in .js files. This plugin supports the basic syntax of Vue.js 3.2, script setup, and CSS variable injection, but the ref sugar, an experimental feature of Vue.js 3.2, is not yet supported. If you have issues with these, please also refer to the FAQ. If you can't find a solution, search for the issue and if the issue doesn't exist, open a new issue. Be aware that depending on the code samples you write in tests, the RuleTester parser property must be set accordingly (this can be done on a test-by-test basis). The default JavaScript parser must be replaced because Vue.js single file components are not plain JavaScript, but a custom file format. vue-eslint-parser is a replacement parser that generates an enhanced AST with nodes that represent specific parts of the template syntax, as well as the contents of the script tag.
