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). -

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. -

Ungoogled Chromium Android
Android build for ungoogled-chromium
Ungoogled Chromium Android is the Android platform build configuration and support tooling for Ungoogled Chromium on mobile devices, enabling privacy-minded users and developers to compile a version of the Chromium browser for Android that excludes Google-dependent services, telemetry, and tracking. This repository contains platform-specific patches, build targets, and integration scripts to adapt the upstream Chromium source for Android while eliminating components like Google Play Services hooks, automatic updater mechanisms, and preconfigured search engines that compromise privacy. The goal is to offer an Android browser that feels familiar in capability and rendering fidelity but does not phone home, engage with proprietary APIs, or leak usage data to third-party providers. Because Android’s ecosystem is heavily tied to Google’s app services, this effort focuses on ensuring core browsing functionality, tab management, extension support (as available), and performance optimizations. -

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. -

Thorium for Android
High-performance, privacy-focused browser built as a fork of Chromium
Thorium-Android is the Android-specific component of the Thorium browser ecosystem, a community-oriented, Chromium-based web browser project focused on improving performance, privacy, and user experience beyond what you typically get from stock Chromium builds. Like its desktop counterparts, Thorium for Android compiles the latest Chromium source with targeted optimizations and patches, aiming for faster loading, smoother rendering, and sensible defaults that emphasize privacy and reduced unwanted data flows. The Android branch adapts these enhancements to work on ARM and ARM64 devices, offering users a familiar yet distinct browsing experience with added performance tuning over standard mobile browsers. It typically includes the same underlying engine that scored high in independent performance benchmarks and leverages optimization flags and compiler improvements to boost responsiveness. -

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. -

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.
