This web browsers are not benchmarked, the opinion in this articles is based on personal use and experience. Keep in mind that a browser to be lite it needs to have some things excluded from itself like extensions and plug-ins example.
One more thing! This is not a ranking list. The browser at number 2 should not be considered better than the one at number 3 for example.
A web browser is not the same thing as a search engine, though the two are often confused. A search engine is a website that provides links to other websites. However, to connect to a website’s server and display its web pages, a user must have a web browser installed.

Pale Moon web browser

Pale Moon is an open-source web browser with an emphasis on customizability; its motto is “Your browser, Your way”. There are official releases for Microsoft Windows and Linux, as well as contributed builds for various platforms.
Pale Moon originated as a fork of Firefox, but has subsequently diverged. The main differences are the user interface, add-on support, and running in single-process mode. Pale Moon retains the highly customizable user interface of the Firefox version 4–28 era. It also continues to support some types of add-ons and plugins that are no longer supported by Firefox, including NPAPI plugins such as Flash Player, and is served by its own ecosystem of extensions. Since version 29.2.0, Pale Moon has discontinued support for extensions that target Firefox, though this restriction will be reverted in a future release.
Key features:
- Uses the pre-Australis user interface (“Strata”) as carried by Firefox during versions 4-28
- Supports extensions built with XUL and XPCOM, which are no longer supported by Firefox
- Supports “Complete Themes”, add-ons which can customize the entire UI of the browser. Firefox no longer supports this and retains limited options for UI customization.
- Supports NPAPI plugins indiscriminately[9], all of which are no longer supported by Firefox
- Supports an ecosystem of add-ons which exclusively target Pale Moon
- Replaces the Gecko browser engine with the Goanna fork
- Always runs in single-process mode, whereas Firefox became a multi-process program
- Defaults to a customizable start page in cooperation with start.me
- Defaults to DuckDuckGo as the search engine instead of Google or Yahoo!
- Uses the IP-API service instead of Google’s for geolocation

SeaMonkey web browser

SeaMonkey is a free and open-source Internet suite. It is the continuation of the former Mozilla Application Suite, based on the same source code, which itself grew out of Netscape Communicator and formed the base of Netscape 6 and Netscape 7.
SeaMonkey was created in 2005 after the Mozilla Foundation decided to focus on the standalone projects Firefox and Thunderbird. The development of SeaMonkey is community-driven, in contrast to the Mozilla Application Suite, which until its last released version (1.7.13) was governed by the Mozilla Foundation. The new project-leading group is called the SeaMonkey Council.
Compared to Firefox, the SeaMonkey web browser keeps the more traditional-looking interface of Netscape and the Mozilla Application Suite, notably the XUL architecture. This allows the user to extend SeaMonkey by modifying add-ons for Thunderbird or the add-ons that were formerly compatible with Firefox before the latter switched to WebExtensions.
Key Features:
- The web browser of SeaMonkey contains a lot of features used in new web browsers like tabbed browsing, pop-up blocking, e-mail, newsgroups, web editing software, spell checking, and an address book.
- Optionally included in the SeaMonkey suite is an IRC chat application.
