Cromite
Cromite a Bromite fork with ad blocking and privacy enhancements
Cromite is an open-source web browser project that originated as a fork of Bromite—a Chromium-based browser focused on ad blocking and enhanced privacy—and continues to evolve with built-in privacy protections and content filtering across Android, Windows, and Linux platforms. It retains the core goal of limiting tracking and intrusive ads by integrating ad blocking directly into the browser engine rather than relying on external extensions, all while striving to reduce telemetry, aggressive analytics, and close manufacturer integration. Cromite emphasizes user choice and control over web content, offering privacy-oriented settings and mitigations such as anti-fingerprinting measures and configurable filters to block unwanted elements. The project extends its focus beyond Android to desktop platforms, building packages that let users benefit from a more private browsing experience without sacrificing compatibility with modern web standards. -

Shorten your time of reading mega bytes of log files! DE 2016-01 Supporting Don HO's NotePad++ see http://notepad-plus-plus.org/ This sources are a dockable pattern search plugin for Notepad++ version 5.1 or later. With this plugin you can search for multiple patterns in any of the opened documents in NotePad++. You may want to tune your search using all fancy tricks from NPP like regular expressions or escaped patterns and give each of the searches different colors. The result will be stored in a dockable window in same ordering as in the origin and a double click allows you to jump to the original position. It is designed to treat log-files of typical size like 60MB. More features can be found in the help dialogue of the plugin. For generating the dll file I use a msdev compiler. If you like to port it to other OSs just let me know your changes and I'll incorporate it. Best Regards, Mattes H.

Selenium
Browser automation framework and ecosystem
Selenium automates browsers. That's it! What you do with that power is entirely up to you. Primarily it is for automating web applications for testing purposes, but is certainly not limited to just that. Boring web-based administration tasks can (and should) also be automated as well. If you want to create robust, browser-based regression automation suites and tests, scale and distribute scripts across many environments, then you want to use Selenium WebDriver, a collection of language specific bindings to drive a browser - the way it is meant to be driven. If you want to create quick bug reproduction scripts, create scripts to aid in automation-aided exploratory testing, then you want to use Selenium IDE; a Chrome and Firefox add-on that will do simple record-and-playback of interactions with the browser. If you want to scale by distributing and running tests on several machines and manage multiple environments from a central point. -
