Free lightweight web browsers that may speed up your web navigation

Brave is a free and open-source web browser based on the Chromium web browser and its Blink engine, announced by the co-founder of the Mozilla Project and creator of JavaScript, Brendan Eich. It blocks website trackers and removes intrusive Internet advertisements. The browser also improves online privacy by sharing less data with advertising customers. One of the selling points of Brave is that it uses its token (BAT, Basic Attention Token) to disrupt the current financial norms of online publishing. The company wants to reward users for browsing the web, while also helping to make advertising less intrusive and more relevant. In another important focus, it wants to use BAT to let readers reward content makers whose websites they visit.

Min Browser is a fast web browser that's designed with advanced features like built-in ad and tracker blocking, smart search and effortless tab management.

It was the default browser in elementary OS Freya.

Mozilla’s Firefox browser didn’t quite make the leap from desktop to mobile, particularly on iOS, but it’s back for a second try with Firefox Focus, a new browser which hopes to be iPhone and Android users’ go-to tool for private web surfing. The mobile browser by default blocks ad trackers and erases your browsing history, including your passwords and cookies. The end result is a simplified browser that may load web pages more quickly, the company claims, given that ads and other web trackers can bog down pages and impact performance.
