    Tor Browser

    Tor Browser

    Browser for using Tor on Windows, Mac OS X or Linux

    Tor Browser enables you to use Tor on Windows, Mac OS X, or Linux without needing to install any software. Tor is a software that bounces your communications around a distributed network of relays run by volunteers. This effectively prevents anyone watching your Internet connection from learning what sites you visit; it prevents the sites you visit from learning your physical location; and allows you access to sites which are blocked. Tor Browser can run off a USB flash drive, comes with a pre-configured web browser to protect your anonymity, and is self-contained (portable).

    geckodriver

    geckodriver

    WebDriver for Firefox

    geckodriver is an implementation of WebDriver, and WebDriver can be used for widely different purposes. How you invoke geckodriver largely depends on your use case. If you are using geckodriver through Selenium, you must ensure that you have version 3.11 or greater. Because geckodriver implements the W3C WebDriver standard and not the same Selenium wire protocol older drivers are using, you may experience incompatibilities and migration problems when making the switch from FirefoxDriver to geckodriver. Generally speaking, Selenium 3 enabled geckodriver as the default WebDriver implementation for Firefox. With the release of Firefox 47, FirefoxDriver had to be discontinued for its lack of support for the new multi-processing architecture in Gecko. Since geckodriver is a separate HTTP server that is a complete remote end implementation of WebDriver, it is possible to avoid using the Selenium remote server if you have no requirements to distribute processes across a matrix of systems.

    Selenium

    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.

    DB Browser for SQLite

    DB Browser for SQLite

    The DB Browser for SQLite

    DB Browser for SQLite (DB4S) is a high quality, visual, open source tool to create, design, and edit database files compatible with SQLite. DB4S is for users and developers who want to create, search, and edit databases. DB4S uses a familiar spreadsheet-like interface, and complicated SQL commands do not have to be learned. This program is not a visual shell for the sqlite command line tool, and does not require familiarity with SQL commands. It is a tool to be used by both developers and end users, and must remain as simple to use as possible in order to achieve these goals. Import and export records as text, import and export tables from/to CSV files, import and export databases from/to SQL dump files, issue SQL queries and inspect the results, examine a log of all SQL commands issued by the application, plot simple graphs based on table or query data.

    Universal Bypass
    Don't waste your time with compliance. Universal Bypass circumvents annoying link shorteners. Universal Bypass bypasses templates that are used on thousands of domains and it would be impossible for me to keep a complete list of domains that are bypassed. You would have to get a new Universal Bypass version and accept its new permissions for each new bypass. Custom Bypasses would be pretty pointless if you could only create them for sites that are already bypassed. Also known in the options as "Give and take the destinations of unbypassable shorteners.", this feature exists to bypass a respectable amount of link shorteners using CAPTCHAs and other forms of backend validation to make sure you've actually waited before you can proceed to the target link, to share this target with other Universal Bypass users, who come across the same link in the future, so they can proceed to the target immediately.
